摘      要：In the present study, a two sided lid-driven mixed convection nanofluid flow with discrete heat sources have been numerically investigated. A two dimensional computational visualization technique is used to study the flow behavior using four different cases;depending on the direction of moving vertical walls with fixed upper and lower walls. Two discrete heat sources of equal lengths are taken on the lower wall and the rest of it is kept insulated. The other walls are kept at constant low temperature. The effect of flow governing parameters such as Reynolds number 1 = Re = 100, Richardson number 0.1 = Ri = 10 and solid volume fraction 0.0 = phi = 0.2 with Prandtl number Pr = 6.2 is studied to understand the fluid flow pattern and the heat transfer effect using isotherms and average Nusselt number.
