Analytical solution for the axi-symmetrical lattice Boltzmann model is obtained for the low-Mach number cylindrical Couette flows. In the hydrodynamic limit, the present solution is in excellent agreement with the result of the Navier–Stokes equation. Since the kinetic boundary condition is...

In this work, we present a new analytical model for the prediction of pollutant dispersion in the atmospheric boundary layer incorporating either the spatial and temporal continuous dependence of the eddy diffusivity. For such, we solve the time-dependent three-dimensional advection–diffusion...
