Résumé

The paper describes a numerical prediction of heat transfer and fluid flow characteristics inside an enclosure bounded by two isothermal wavy walls and two adiabatic straight walls. Governing equations were discretized using the finite-volume method with collocated variable arrangement. Simulation was carried out for a range of wave ratio (defined by amplitude/average width) 0.00-04, aspect ratio (defined by height/average width) 1.0-2.0, Grashof number Gr= 10(0)-10(7) for a fluid having Prandtl number 0.7. Streamlines and isothermal lines are used to present the corresponding flow and thermal field inside the enclosure. Local and global distributions of Nusselt number are presented for the above configuration. Velocity profiles are presented for some selected locations inside the enclosure.
