T1 Lattice Boltzmann Method for Laminar Forced Convection in a Channel with a Triangular Prism JF Heat Transfer Research JO HTR YR 2011 FD 2011-12-20 VO 42 IS 4 SP 359 OP 377 K1 Lattice Boltzmann Method (LBM) K1 laminar forced convection K1 channel with triangular prism AB The Lattice Boltzmann Method (LBM) is applied to computationally investigate the laminar flow and heat transfer of an incompressible fluid with constant material properties in a two-dimensional channel with a built-in triangular prism. Not only the momentum transport, but also the energy transport is modeled by LBM. A uniform lattice structure with a single time relaxation rule is used. The flow is investigated for different Reynolds numbers, while keeping the Prandtl number at a constant value of 0.7. The results show how the presence of a triangular prism affects the flow and heat transfer patterns for the steady-state and unsteady/periodic flow regimes. As an assessment of the accuracy of the developed LBM code, the results are compared with those obtained by a commercial CFD code. It is observed that the present LBM code delivers results that are of similar accuracy to the well-established CFD code.
