| description | The understanding of mixed convection heat transfer in cavity is crucial for studying the energy consumption and efficiency in many engineering devices. In the present work, the hybrid nanofluid (Al<sub>2</sub>O<sub>3</sub>-Cu-Water) is employed to increase the heat transfer rate in a double lid-driven rectangular cavity. The bottom movable horizontal wall is kept at a high temperature while the top movable horizontal wall is kept at a low temperature. The sidewalls are insulated. The mass, momentum and energy equations are numerically solved using the Finite Volume Method (FVM). The SIMPLE algorithm is used for pressure-velocity coupling. Parameters such as Reynold’s number (<inline-formula><math display="inline"><semantics><mrow><mi>R</mi><mi>e</mi></mrow></semantics></math></inline-formula>), Richardson number (<inline-formula><math display="inline"><semantics><mrow><mi>R</mi><mi>i</mi></mrow></semantics></math></inline-formula>), moving wall direction, solid volume fraction, and cavity length are studied. The results show that the hybrid nanofluid in the rectangular cavity is able to augment the heat transfer significantly. When <inline-formula><math display="inline"><semantics><mrow><mi>R</mi><mi>e</mi></mrow></semantics></math></inline-formula> is high, a big size solid body can augment the heat transfer. Heat transfer increases with respect to <inline-formula><math display="inline"><semantics><mrow><mi>R</mi><mi>i</mi></mrow></semantics></math></inline-formula>. Meanwhile, the local Nusselt number decreases with respect to the cavity length. |
