Predictions of lid-driven flow and heat convection in an arc-shape cavity

The present study is aimed to study flow behaviors and heat transfer characteristics for a lid-driven air flow within an arc-shape cavity. Stream function-vorticity formulation representing the laws of conservation in mass, momentum, and energy in terms of a curvilinear coordinate is solved numerically. Attention has been focused on the effects of the inertial and buoyant forces exerted on the fluid. Results for various Reynolds numbers (Re), Grashof numbers (Gr), and inclination angles (phi) are presented. The ranges of these parameters considered in this study are 100 less than or equal to Re less than or equal to 2000, 0 less than or equal to Gr less than or equal to 10(8), and 0 less than or equal to phi less than or equal to 2 pi.
