RÉSUMÉ

In the present analysis flow and heat transfer of a viscous fluid in a semiporous curved channel coiled in a circle of radius R through a Darcy porous medium with convective boundary condition is discussed. In addition, the effects of thermal radiation are also considered. The mathematical model of the flow and heat transfer problem is developed by using a curvilinear coordinate system. Similar solutions are computed numerically by a shooting method. The results are also validated with the well-known finite difference technique known as the Keller-Box method. Fluid velocity, temperature, skin friction coefficient, and rate of heat transfer at the wall are discussed through graphs and tables for the various values of the involved parameters.
