Summary of Activities/Interests
Professor Strieder's primary research interests are in the areas of thermodynamics of equilibrium and irreversible processes, heat and mass transport in porous media, interfacial phenomena, chemical engineering reaction systems, statistical mechanics, kinetic theory and applied mathematics.
Heterogeneous two-phase materials are often encountered in engineering practice, and a knowledge of their thermal transport coefficients is important in many heat transfer calculations. Current heat transfer research programs include exact solutions for high temperature radiation heat transport across a number of regular spherical, cylindrical and ellipsoidal cavity geometries encountered in insulating ceramic brick, solid nuclear fuel elements and high temperature gas-solid reactions. Rigorous solution of the radiation heat transfer multiple scattering problem across random void-solid packings are being formulated in order to calculate the effective boundary emissivity coefficient of packed and fluidized beds, as well as the internal void radiation transport coefficient. Other areas of active interest are conductive heat transport in composite materials; heat transport coupled with ice melting, conductive and convective heat transport in porous beds and low-temperature cryogenic insulation.
Interfacial phenomena can play a significant role in both chemical reaction and separation processes. Equations for the effective surface diffusivity and surface tortuosity in terms of the fundamental constants of the molecular diffusion and adsorption surface processes and the structure of the porous medium are being developed. Other research programs include the effects of interfacial cell wall resistance in heart muscle tissue transport and the statistical mechanics of interfacial separation processes.
The effects of volume change on mass transport in coupled gas-solid reaction systems both on the level of the individual reacting particle and within a compact of particles can influence a number of chemical engineering operations. The selectivity of the parallel oxide and sulfate reactions in the reduction of metal sulfide particles is being studied to determine the importance of particle size and the different volume changes of each product. The experimental study and theoretical modeling of the reaction-bonding synthesis of silicon nitride from silicon powder compacts is a current area of investigation.
