    Notes: The application of thermal diffusion to the separation of a pair of salts in aqueous solution was investigated. Experiments were conducted with the system copper sulfate-cobalt sulfate-water with both static, single-stage cells and continuous, countercurrent flow contactors (or columns) of the horizontal Jury-Von Halle type which utilizes flow through a porous membrane. Design equations for the continuous columns were developed, based on an idealized representation of the combined hydrodynamic and diffusion problem. Data from the single-stage experiments were used in conjunction with these equations to predict stage separation factors and transfer unit heights. These mass transfer parameters were measured under various operating conditions on continuous units of two different sizes.The effects of size and operating conditions on the separation factor and transfer unit height were successfully predicted by use of the design equations. The accurate calculation of these quantities directly from single-stage separation data was less successful, owing to the highly idealized nature of the mathematical model employed.

    On-line optimizing control of a packed-bed immobilized-cell reactor (1988)

    Notes: On-line optimizing control has been used to find and track the economically optimal operating conditions of a packed-bed reactor. The continuous reactor under study converts the ammonium salt of fumaric acid to aspartic acid using whole cells immobilizing in K-carrageenan beads. The on-line optimizing control was performed using a leastsquares recursive estimation algorithm with a variable forgetting factor to estimate the parameters in a linear discrete-time model. A Newton optimization procedure used these parameters to calculate the direction and distance to the optimal conditions. Features found to enhance the speed and stability of the algorithm included the use of a variable forgetting factor algorithm, both low- and high-pass filtering of the data, outlier rejection, and linearizing input-outupt transformations.

    Binding of an antifreeze polypeptide to an ice/water interface via computer simulation (1995)

    Notes: The interaction between a winter flounder antifreeze polypeptide and an ice/water interface was studied using Molecular Dynamics computer simulation techniques to study the mechanism of action of this class of antifreeze molecules. Simple Point Charge models were used for the water molecules, and a molecular mechanics program (CHARMM) was used to construct the model for the polypeptide. A (2021) face was exposed on the ice surface, as this is believed to be the experimentally favored ice face for peptide binding. The polypeptide binds strongly to the ice surface even though it was placed with its four polar threonine (Thr) groups pointing away from the ice surface. This tested the previously advanced hypothesis that adsorption occurs primarily between these groups and the ice due to a matching of the spacing between oxygen atoms in the ice lattice and the polar Thr residues. As well as contacts with other polar groups on the peptide, the binding to the ice produces a good steric fit of the peptide with the corrugated ice interface. The presence of the peptide did not induce any melting of the ice at 200 K.

    Heat transfer from two-phase boundary layers on isothermal cylinder: Influence of drop trajectory (1980)
    Hoboken, NJ : Wiley-Blackwell

    Notes: The influence of drop trajectories on boundary layer structure and heat transfer coefficient is determined for a binary spray flow over the upstream surface of an isothermal cylinder. Governing equations are solved for drop trajectories upstream of the cylinder, the laminar liquid boundary layer adjacent to the cylinder surface, and the outer laminar vapor boundary layer. Velocity, temperature, and mass concentration profiles throughout the double boundary layers are shown to depend on flow parameters involving drop size and velocity. The critical conditions for which the liquid film dries out are identified for a range of drop size and velocity, defining the transition from the liquid film to the dry wall flow regime. Theoretical results for heat transfer are shown to correlate existing experimental data.
