Abstract

A numerical study of incompressible laminar mixed convection in the entrance region of 2-D vertical and inclined channels using the regularized lattice Boltzmann method is presented. Individual distribution functions with lattice types D2Q9 and D2Q5 are considered to solve fluid flow and thermal fields, respectively. Reynolds number is held constant at 100 and Grashof number is varied from 103 to 106. The channel inclination angle is varied from 0 to 60°. The aspect ratio of channel is equal to 5. Predicted velocity and temperature fields are in good agreement with velocity and temperature fields found from the finite volume code Fluent.
