Structural Stability in Resonant Penetrative Convection in a Brinkman–Forchheimer Fluid Interfacing with a Darcy Fluid

The resonant penetrative convection in a Brinkman–Forchheimer fluid interfacing with a Darcy fluid is considered. It is our main purpose to study the continuous dependence of the solution on changes in the heat source and the continuous dependence of the solution on the Forchheimer coefficient.
