要約

Forced convection heat transfer over an electronic board mounted with several shapes of obstacles, consisting of three cylinders and three cubes, is investigated using the lattice Boltzmann method (LBM). Incompressible flow of field through the obstacles over a sheet is assumed. The simulations are performed at Pr = 0.71. Studies are carried out for flow, with Reynolds numbers ranging from 250 to 1000. Uniform heat fluxes through the base of obstacles are assumed. Results show that LBM is suitable for the study of heat transfer in forced convection problems. Results indicate that an increase in Reynolds number yields to the removal of a higher quantity of energy from obstacle faces. Results also show that reducing the distance between obstacles makes the flow deviate and accelerate in the vicinity of faces and causes an increase in the rate of convective heat transfer from obstacles.
