ATMOSPHERIC DISPERSION SIMULATIONS - PASSIVE GAS MIXTURE FLOW
Kyncl M., Pelant J.
pages 367 - 370, full text

Here we work with the system of equations describing the non-stationary compressible turbulent multi-component flow in the gravitational field, and we focus on the numerical solution of these equations. The mixture of perfect inert gases is assumed. The RANS equations are discretized with the use of the finite volume method. The exact solution of the modified Riemann problem (original results) is used at the boundary faces. The roughness of the surface is simulated using the alteration of the specific dissipation at the wall. The presented computational results are computed with the own-developed code (C, FORTRAN, multiprocessor, unstructured meshes in general).
