The effects of corrugation frequency and Grash of numbers on local Nusselt number, total heat flux, vertical velocity and temperature distributions at the horizontal mid-plane have been investigated. Corrugation frequency from 1 to 3 and Grash of number from 10³ to 10⁵ has been considered in this study. The results are compared with the available information on natural convection and fluid flow.</span>
