Abstract: H05.00008 : Modelling the Navier-Stokes-Darcy-Boussinesq system
9:31 AM–9:44 AM
Additionally, we investigate various parameter regimes of the system and present a notable case with altering the depth ratio of the two regions. In these superposed fluid-porous media systems, the ratio of the fluid height to the porous medium height exerts a significant influence on the behavior of the coupled system with its impact on resulting convection cells. Altering the depth ratio slightly can trigger a transition from deep convection where convection cells encapsulate the entire domain to shallow convection where cells occupy only the fluid region. With current interest surrounding superposed fluid-porous medium systems in numerous projects of industrial, environmental, and geophysical importance (oil recovery, carbon dioxide sequestration, contamination in sub-soil reservoirs, etc.), being able to predict the critical depth ratio where this convection shift occurs is particularly timely.
