MIXED CONVECTION FLOW AND HEAT TRANSFER IN A LID-DRIVEN CAVITY SUBJECTED TO NANOFLUID: EFFECT OF TEMPERATURE, CONCENTRATION AND CAVITY INCLINATION ANGLES
要約
In this work, mixed convection in a lid-driven cavity with an inside heated obstacle at various cavity inclination angles with new formulation of variable properties was studied numerically. The bottom and vertical walls are kept insulated, whereas the top moving wall is maintained at a low temperature Tc. An obstacle of a relatively higher temperature Th is located on the bottom wall of the cavity. The governing equations are discretized using the finite volume method and SIMPLER algorithm. Using a developed code, we accomplished a parametric study and analyzed the influence of important parameters, such as the Richardson number, solid volume fraction of Al2O3 nanoparticles, cavity inclination angles, height of a hot obstacle, and the nanofluid temperature on the thermal behavior and flow characteristics.
