| description | The aim ofthe present study is to investigate the effects of the rectangular prism onforced convection in a channel with the Lattice Boltzmann Method (LBM). In thiscontext, numerical analysis of steady and unsteady incompressible flow and heattransfer has been done in a two-dimensional straight parallel channel. Momentumand energy transport are modelled with LBM. This study is used as a singlerelaxation time rule with a uniform square lattice structure. DifferentReynolds numbers (50 and 1000) and constant Prandtl number value (0.7) havebeen investigated. In this study Nusselt number has been calculated for channelflow with rectangular prism and it was compared with an empty channel.Streamlines and isotherms were presented for the above-mentioned cases. LBMresults were validated by commercial CFD code with the same conditions. It isfound from results that Nusselt number with a rectangular prism in a channelwas increased and the flow goes to transient form at Re=1000. Also, LBM coderesults are similar accuracy with commercial CFD code. |
