Flow simulations using two dimensional thermal Lattice Boltzmann method

Lattice boltzmann method is implemented to study hydrodynamically and thermally developing steady laminar flows in a channel. numerical simulation of two-dimensional convective heat transfer problem is conducted using two-dimensional,nine directional d2q9 thermal lattice boltzmann arrangements. the velocity and temperature profiles in the developing region predicted by lattice boltzmann method are compared against those obtained by ansys-fluent. velocity and temperature profiles as well as the skin friction and the nusselt numbers agree very well with those predicted by the self-similar solutions of fully developed flows. it is clearly shown here that thermal lattice boltzmann method is an effective computational fluid dynamics (cfd) tool to study nonisothermal flow problems. copyright © 2012 saeed j. almalowi and alparslan oztekin.
