Numerical study on mixed convection in an inclined lid-driven cavity with discrete heating

The present investigation deals with numerical analysis on mixed convection in an inclined square cavity with different sizes and locations of the heater. The left wall is heated fully or partially with higher temperature whereas the opposite wall is kept with lower temperature. In the left wall, three different sizes and locations of the heater are considered. The governing transformed equations are solved numerically using the finite volume method. Simulations are performed on different Richardson numbers, different sizes and locations of the heater and the cavity inclination angles. It is observed that the high heat transfer is found at cavity inclination angle of γ = 30° in the buoyancy convection dominated regime when the heater is located at the middle of the cavity.
