Abstract
The paper is devoted to construction of a numerical model and computations of continuously stratified fluid flows in field of external mass forces accounting for dissipative factors, viscosity and diffusion. Mathematical model is based on the fundamental set of differential equations of inhomogeneous multicomponent fluid mechanics. Solution of the problem is constructed numerically in the completenon-linear formulation using finite volume method in frame of the open source package OpenFOAM. To take in to account the stratification and diffusion effects a new own solver, stratifiedFoam, was developed and tested using the standard and extended libraries of the package. A particular attention is focused at construction of a high quality computational grid which satisfies basic requirements for resolution of all the microscales of the problem in high-gradient regions of the flow. The calculations performed in parallel regime on computational facilities of the web-laboratory UniHUB demonstrated a pretty high efficiency of the proposed numerical model and a good agreement with the experimental data.
