AB - <p style="text-align: justify;">The main goal of this paper is to develop the coupled double-distribution-function
(DDF) lattice Boltzmann method (LBM) for simulation of subsonic and transonic
turbulent flows. In the present study, we adopt the second-order implicit-explicit
(IMEX) Runge-Kutta schemes for time discretization and the Non-Oscillatory and Non-Free-Parameters
Dissipative (NND) finite difference scheme for space discretization.
The Sutherland&#39;s law is used for expressing the viscosity of the fluid due to considerable
temperature change. Also, the Spalart-Allmaras (SA) turbulence model is incorporated
in order for the turbulent flow effect to be pronounced. Numerical experiments
are performed on different turbulent compressible flows around a NACA0012
airfoil with body-fitted grid. Our numerical results are found to be in good agreement
with experiment data and/or other numerical solutions, demonstrating the applicability
of the method presented in this study to simulations of both subsonic and transonic
turbulent flows.</p>
