Two-component fluid convective flow in thin gaps

The goal of the present study is to investigate numerically and experimentally the peculiarities of two-component viscous fluid flow in a thin plane channel, and to determine entrapment and flushing out one component by the other. Experiments on miscible displacement of fluids in Hele-Shaw cells were conducted under microgravity conditions. Extensive direct numerical simulations allowed to investigate the sensitivity of fluid flow to variation of values of the main governing parameters. Validation of the code was performed by comparing the results of model problems simulations with experiments.
