Both square enclosure and cylinder are maintained at constant temperature and air filled the enclosure. Boundary conditions for fluid flow and temperature fields at curved boundaries are second order schemes. The buoyancy effect is modeled by applying the Boussinesq approximation to the density distribution function. The computed results show that by increasing amplitude or number of undulations or changing the angle might change the heat transfer coefficient and has profound influence on the temperature and fluid field.
