This paper presents a solution methodology for multiobjective optimization problems in the context of models for the placement of components on printed wiring boards (PWB's). The methodology combines the use of a flow and heat transfer solver, a gene

Theoretical analysis and numerical calculations are performed to characterize the unsteady two-dimensional conduction of thermal energy in an idealized honey bee comb. The situation explored corresponds to a comb containing a number of brood cells oc

Results of a numerical study concerning two-dimensional time-dependent laminar flow near a square bluff body are reported. The configuration investigated is that of flow around a square block in contact with a moving wall, with fluid approaching the

Preliminary experimental results are reported for the structure of the flow due to the collision of a pair of boundary layers driven towards each other by buoyant forces along a vertical wall. Of the possible parameters characterizing the flow, a Ray

Numerical modeling of fluid-particulate turbulent flow transport processes, including erosion, cannot substitute (at least for the present) good experimentation. Notwithstanding, the calculation approach offers a viable, relatively inexpensive and co
Two models have been developed for predicting low Reynolds number turbulent flows in the free and mixed convection regimes. One, the KEM model, is based on the notion of eddy diffusivities for momentum and heat. The other, the ASM model, is based on
