Rayleigh Numbers

Numerical solutions are obtained for fluid flow and heat transfer in a cubic enclosure with a vertical adiabatic partition. The two zones of the enclosure are connected by a single rectangular opening. The partition is oriented parallel to the isothermal sidewalls, one of which is heated and the other cooled while the remaining walls are adiabatic. Results have been presented for air for the Rayleigh numbers in the range 104−107. The width of the opening is held fixed while the height, relative to the enclosure height, is varied from 0.25 to 0.75. The effects of various parameters on the flow structure and heat transfer are investigated. The results of the three-dimensional simulation have also been compared with those for the corresponding two-dimensional configurations.

Wall Interactions

Three-dimensional simulation of turbulent gas-solid flow with heat transfer for a vertical pipe is performed in this study and the results are presented. The approach is based on an Eulerian/Lagrangian four-way interaction formulation considering turbulent hydrodynamic and thermal intensities and time scales equations. Inter-particles and particle-wall interactions are accounted for with an inelastic collision model. Numerical model validation is performed for an upward pipe gas-solid flow with constant wall heat transfer.
