This work aims to determine how the temperature gradient orientation affects heat exchange between two superposed fluid layers separated by zero wall thickness. The finite volume method (FVM) has been developed solve governing equations of both layers. To achieve coupling layers, flow continuity with no-slip condition at interface was adopted. lower part space is filled a nanofluid while upper pure layer. We have explored cases orientation: parallel gravity forces our system and...
This numerical study is intended for the analysis of thermal convection induced by buoyancy forces generated within a conical annular porous gap.
