    Description / Table of Contents: Zusammenfassung Eine analytische Lösung des Problems der turbulenten Wärmeübertragung in Rohren mit innerer Wärmeerzeugung und isolierender Wandung wird vermittels eines neu entwickelten Modells für das Wirbelleitvermögen angegeben. Die Ergebnisse stimmen mit den zugänglichen experimentellen Werten innerhalb eines ausgedehnten Bereiches der Prandtl-Zahl (0.02–10.5) befriedigend überein.
    Notes: Abstract An Analytic solution is presented of the problem of turbulent heat transfer in pipes with internal heat generation and insulated wall by applying a recently-developed eddy conductivity model.

    Description / Table of Contents: Zusammenfassung In diesem Bericht ist das Problem der laminaren natürlichen Konvektionsströmung an einem dünnen Kegelstumpf behandelt. Die maßgebliche Differentialgleichung ist durch eine Verbindung von Quasilinearisation und Differenzenverfahren gelöst. Eine numerische Lösung für Pr=0.7 wird für verschiedene Werte eines Krümmungsparameters angegeben. Es ist gezeigt, daß in solchen Strömungen dieser Krümmungsparameter eine große Bedeutung besitzt.
    Notes: Abstract The problem of laminar, natural convection flow over a slender frustum of a cone is treated in this paper. The governing differential equations are solved by a combination of quasi-linearization and finite-difference methods. Numerical solutions are obtained for Pr=0.7 and for a range of values of the transverse curvature parameter. It is shown that the effect of transverse curvature is of great significance in such flows.

    The effect of radiation on transient natural convection past a doubly infinite plate (1984)

    Description / Table of Contents: Zusammenfassung Der vorliegende Bericht befaßt sich mit der Untersuchung der transienten Vorgänge bei gleichzeitiger freier Konvektion und Strahlung an einem zähen Fluid entlang einer unendlichen isothermen ebenen Platte. Um das komplizierte Problem zu vereinfachen, wird eine inkompressible Strömung angenommen. Normalerweise ist die exakte numerische Lösung dieses Problems sehr langwierig. Berücksichtigt man jedoch ein optisch dichtes, strahlendes Gas wie es durch die Rosselandsche Diffusionsnäherung ausgedrückt wird, ist die Lösung wesentlich einfacher. Zudem führt dieser Fall zu einer kompletten Ähnlichkeitstransformation der beschreibenden partiellen Differentialgleichungen in einen Satz von gewöhnlichen Differentialgleichungen. Eine exakte numerische Lösung wird erzielt für eine PrandtlZahl von 0.733 und einem großen Bereich der beteiligten Parameter.
    Notes: Abstract The present research note is concerned with the transient (short time) simultaneous free convection and radiation analysis of a viscous fluid along a doubly infinite vertical isothermal flat plate. To simplify a very complicated problem, an incompressible flow field is used in the analysis. Generally, the exact numerical solution of this problem is quite lengthy. However, by considering an optically thick radiating gas, expressed by the Rosseland diffusion approximation, the solution is much simpler. Moreover, this case leads to a complete similarity transformation of the governing partial differential equations into a set of ordinary differential equations. An exact numerical solution is obtained of the resulting ordinary differential equations for a Prandtl number equal to 0.733 and for a wide range of involved parameters.

    Notes: Abstract The problem of laminar, natural convection flow over a vertical frustum of a cone is treated in this paper. The thermal boundary condition at the wall include both the constant wall temperature and the constant wall heat flux cases. The governing differential equations are solved by a combination of quasilinearization and finite-difference methods. Numerical solutions are obtained for a range of Prandtl numbers. The solutions are found to approach to the solutions for a full cone if the flow is far downstream or the radius of the cross-section at the leading edge is very small.

    Optimal shape remodelling of linearly elastic plates using finite element methods (1984)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 20 (1984), S. 1823-1840 
    Details
    ISSN: 0029-5981

    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Mathematics , Technology
    Notes: The optimality conditions for the optimal shape remodelling of linearly elastic plates are obtained by introducing the total variation of a function defined on a variable domain, although the variation of a function has been taken on a fixed domain in most literature on calculus of variations. Using these optimality conditions, a solution scheme involving an iterative algorithm is proposed, together with several numerical examples.
