要約

The paper presents the application of the lattice Boltzmann equation (LBE) method to the numerical prediction of a laminar and convective-heated transfer through a two-dimensional obstructed channel flow. The obstruction is carried out by obstacles including two located on the lower wall and the other on the upper wall of the channel. The computations were initially validated against available results in literature, and then the results are presented in terms of the flow Reynolds number, the size of obstacles and the distance (w) between the two lower obstacles. In light of the obtained results, we can conclude that the heat transfer depends highly of these parameters.
