Abstract
⺠We derive a body force model expression in the lattice Boltzmann (LB) method. ⺠This model recovers exactly the steady incompressible Navier-Stokes equations. ⺠The analysis is performed theoretically (Chapman-Enskog analysis) and numerically. ⺠The correct form of the LB body force model differs from the time-dependent case. ⺠The model yields the most accurate results for varying body forces in steady flows.
