Description: In this paper we revisit the a priori turbulent flame speed tabulation (TFST) technique for a given parameter space within the region of flamelet combustion-regimes. It can be used as a subgrid-scale (SGS) model in Large Eddy Simulation (LES). In a first step, stationary laminar flamelets are computed and stored over the progress variable following the ideas of flamelet generated manifolds (FGM). In a second step, the incompressible one-dimensional Navier-Stokes equations supplemented by the equation for the progress variable are solved on a grid that resolves all turbulent scales. Additionally, turbulent transport is implemented via the linear eddy model (LEM). The turbulent flame structures are solved until a statistically stationary mean value of the turbulent flame speed has been reached. The results are stored in a table that could be used by large scale premixed combustion models, e.g. front tracking schemes. First results are compared quantitatively with direct numerical simulations (DNS) taken from literature. Then it is illustrated in one example how the new method could help to fix constants in algebraic models for turbulent flame speeds. Further it is shown how the technique can be extended to incorporate turbulent strain effects. Finally we investigate the effect of the use of detailed and tabulated chemistry under unsteady conditions.

Description: A world-wide used program for the simulation of fire-induced flows is the Fire Dynamics Simulator (FDS) which originally was developed for a purely serial execution on single-processor computing systems. Due to steadily increasing problem sizes and accuracy requirements as well as restrictions in storage capacity and computing power on single-processor systems, the efficient simulation of the considered fire scenarios can only be achieved on modern high-performance systems based on multi-processor architectures. The transition to those systems requires the elaborate parallelization of the underlying numerical methods which must guarantee the same result for a given problem as the corresponding serial execution. Unfortunately, one fundamental serial serial solver of FDS, the pressure solver, only possesses a low degree of inherent parallelizm. Its current parallelization may cause additional numerical errors, casually leading to significant losses of accuracy or even numerical instabilities. In order to ensure that the parallelization errors are limited by the leading error of the numerical scheme such that second order convergence for the whole method can be acchieved, optimized parallelization concepts must be designed. With respect to these considerations this articles gives an overview of the current parallel pressure solver as well as the problems related to it and presents an alternative method, SCARC, to overcome the existing complicacies. Part I explains the theory, concept and implementation of this new strategy, whereas Part II describes a series of validation and verification tests to proof its correctness.

Description: Because CFD programs, like FDS, generally consist of a large number of different components representing the variety of participating numerical algorithms and chemical / physical processes, it is nearly impossible to verify such codes in their entirety, for example with comparisons of fire tests. Instead, a careful verification and validation with respect to the underlying mathematical conditions and applied numerical schemes is indispensable. In particular, error cancelations between single program components can only be detected by such detailed component-level tests. In part I of this article series a conceptual deficiency of the FDS program package with regard to multi-mesh computations was illustrated and an alternative domain decomposition strategy FDS-ScaRC was introduced. In this second part we will present the structure of a comprehensive test concept and the needs for a more mathematically and numerically orientated test procedure that is much more suited for a reliable evaluation than only a simple visual comparison of the numerical results with experimental fire tests. After a general introduction of our test concept we will demonstrate the high potential of the new FDS-\scarc{} technique compared to the FDS-FFT technique which is used in the FDS program package as yet. Based on this concept, we will present a comprehensive set of analytical and numerical test results.

Description: In this paper we propose a technique for a priori turbulent flame speed tabulation (TFST) for a given parameter space in standard combustion-regime diagrams. It can be used as a subgrid-scale (SGS) model in Large Eddy Simulation (LES). In a first step, stationary laminar flamelets are computed and stored over the progress variable following the ideas of flamelet generated manifolds (FGM). In a second step, the incompressible one-dimensional Navier-Stokes equations supplemented by the equation for the progress variable are solved on a grid that resolves all turbulent scales. Additionally, turbulent transport is implemented via the linear eddy model (LEM). The turbulent flame structures are solved until a statistically stationary mean value of the turbulent flame speed has been reached. The results are stored in a table that could be used by large scale premixed combustion models, e.g. front tracking schemes. Results are compared to an algebraic model and to direct numerical simulations (DNS).

Publication Date: 2016-06-09

Description: The influence of thermal stratification on autoignition at constant volume and high pressure is investigated under turbulent conditions using the one-dimensional Linear-Eddy Model (LEM) and detailed hydrogen/air chemistry. Results are presented for the influence of initial temperature inhomogeneities on the heat release rate and the relative importance of diffusion and chemical reactions. The predicted heat release rates are compared with heat release rates of Chen et al. and Hawkes et al. obtained by two-dimensional Direct Numerical Simulations (DNS). Using the definition of Chen et al. for the displacement speed of the H2 mass fraction tracked at the location of maximum heat release, and a comparison of budget terms, different combustion modes including ignition front propagation and deflagration waves are identified and the results are compared to the DNS data. The LEM approach shows qualitatively and quantitatively reasonable agreement with the DNS data over the whole range of investigated temperature fluctuations. The results presented in this work suggest that LEM is a potential candidate as a sub-model for CFD calculations of HCCI engines.

Notes: An Hand theoretischer Überlegungen wurden für die polarographische Reduktion des Formaldehyds in wässriger Lösung Beziehungen abgeleitet, die den Verlauf des Grenzstromes, der ganzen Stromspannungskurven und des Halbwellenpotentials bei pH-, Temperatur- und Aldehyd-Konzentrationsvariation qualitativ, in einigen Fällen sogar quantitativ beschreiben können. Diese Überlegungen fussten auf der Annahme, dass die Formaldehydwelle nicht durch die Diffusion, sondern durch die Dehydratationsgeschwindigkeit des in wässriger Lösung fast ausschliesslich vorliegenden Methylenglykols zum allein reduzierbar angenommenen, unhydratisierten, monomeren CH2O begrenzt werde.Die hauptsächlichsten experimentellen Befunde wurden beschrieben. Sie erstrecken sich auf pH-, Temperatur- und Formaldehyd-Konzentrationsvariation in gepufferten und ungepufferten Grundlösungen. Die pH-Abhängigkeit der Dehydratationsgeschwindigkeit des Methylenglykols konnte direkt gezeigt werden. Die Diffusionskonstante von Methylenglykol wurde experimentell bei 20° C ermittelt. Die Lage des Hydratationsgleichgewichtes in verdünnter, wässriger Formaldehydlösung wurde ultraviolett-spektrographisch bei verschiedenen Temperaturen, unter Verwendung besonders grosser Schichtlängen, näher ermittelt.

Notes: Es wurde eine Methode zur Bestimmung der Reduktions-Oxydations-Potentiale von photographischen Entwicklern beschrieben. Die Abhängigkeit dieser Potentiale vom PH-wert der Lösungen wurde ermittelt. Jedes gemessene Potential wurde in Beziehung gebracht mit der Entwicklungszeit, die notwendig war, um eine Graukeilkopie in der Lösung zu einem bestimmten Gamma-Wert, im vorliegenden Fall zu γ = 0,60, zu entwickeln.Die Gamma-Werte wurden nach einer vereinfachten Methode ermittelt.Eine allgemein gültige Beziehung zwischen Potential der Lösung und Entwicklungszeit konnte nicht gefunden werden.Die Art der Funktion log Entwicklungszeit/Potential beeinflusst die Arbeitsweise der Entwickler. Es konnte gezeigt werden, dass Entwickler mit grossen Werten der Neigung der Kurve log Entw.-zeit/Potential bei Potentialänderung durch beträchtliche Variation der Entwicklungsgeschwindigkeit reagieren.Die Einteilung der Entwickler in Oberflächen- und Tiefenentwickler lässt sich auf die Grösse der Neigung der Kurve log Entw.-zeit/Potential zurückführen. Oberflächenentwickler sind solche mit kleinen, Tiefenentwickler solche mit grossen Werten der Neigung.

Notes: Die bisher bekannt gewordenen Verfahren zur Bestimmung der Anzahl der theoretischen Böden in Bodenkolonnen bzw. der Austauscheinheiten in Füllkörperkolonnen sind in der praktischen Anwendung für den Chemiker und Techniker im allgemeinen zeitraubend und umständlich. Hier wird von einem Verfahren berichtet, das die Boden- und Austauschzahlen aus Nomogrammen bzw. Diagrammen bei hoher Genauigkeit sofort abzulesen gestattet.

Notes: Bei dem von H. C. Urey und Mitarb. entwickelten chemischen Isotopentrennverfahren stellt die Bewegung der meist hochaggressiven Flüssigkeiten eine der wesentlichsten apparativen Schwierigkeiten dar. Die Säuren, Laugen und Salzlösungen müssen über Zeiträume von mehreren Monaten mit genauer Dosierung gepumpt werden, wobei die Fördervolumina häufig nur in der Größenordnung von einigen 10 cm3/h liegen. Bei der von uns in München durchgeführten Anreicherung des 15N konnten diese Schwierigkeiten mit einem Spezialtyp der auch von Urey und Mitarb. verwendeten Schlauchpumpe überwunden werden. Da diese Pumpe, die sich inzwischen im jahrelangen Dauerbetrieb bestens bewährt hat, auch für andere Probleme der chemischen Labor- und Betriebspraxis geeignet ist, wird sie im folgenden beschrieben.
