Abstract
Mixed convection of Cu-water nanofluid in a square enclosure with upper and lower moving lid has been investigated numerically. Non-uniform heating is imposed on the left wall, and the right wall is cooled at a constant temperature. Upper and lower walls are taken to be adiabatic. Finite volume-based SIMPLE algorithm has been used to solve the nonlinear equations. Results are presented graphically to describe the effect of nanoparticle volume fraction (\(0.0 \le \phi \le 0.2\)), Richardson number (\(0.1 \le Ri \le 10.0\)) and the moving walls (upper and lower) on flow field, thermal field and heat transfer rate at a fixed value of Reynolds number (\(Re=100\)). Results show that heat transfer rate increases remarkably with the addition of nanoparticles. Non-uniform temperature distribution on the left wall affects the thermal field.
