摘要：Analysis of Prandtl number effect on forced convective flow and thermal field characteristics inside an open cavity with porous wavy isothermal wall using water-CuO nanofluid have been performed numerically. The upper and lower surfaces are of temperature T h . The fluid enters from left and exits from right with initial velocity U i and temperature T i . Governing equations are discretized using the Finite Element Method. Simulation is carried out for a range of Prandtl number, Pr (from 1.47 to 8.81) and wave amplitude A (from 0 to 0.15) while Reynolds number, Re =100; Darcy number, Da = 100 and solid volume fraction, = 5%. Results are presented in the form of streamlines, isothermal lines, rate of heat transfer, average temperature of the fluid and velocity at mid-height of the channel for various Pr and A . Increasing Pr and lessening A causes the enhancement of heat transfer rate. © 2013 JSR Publications. ISSN: 2070-0237 (Print); 2070-0245 (Online).
