Generalized wall functions in application to high-Reynolds-number turbulence models are derived. The wall functions are based on transfer of a boundary condition from a wall to some intermediate boundary near the wall (usually the first nearest to the wall mesh point but that is not obligatory). The

A thermal lattice BGK model with doubled populations, together with a new boundary condition for temperature and heat flux, is proposed to simulate the two-dimensional natural convection flow in a cavity. Numerical results for the problem of insulated horizontal walls and vertical walls at different
## Abstract Twoβdimensional numerical computation is performed for an unsteady laminar flow. Spatially the periodic boundary conditions are adopted in the streamwise direction and the adequacy of this treatment is studied by varying the computational domain size. The following results were obtained
## Abstract This paper is a sequel to the recent numerical study of thermally driven vortices by the authors. the model developed earlier is used as a basis for comparing a variety of radial boundary conditions and to assess their suitability for models of βtallβthinβ atmospheric vortices, in parti
