Investigation of heat transfer due to isothermal heater in irregular porous cavity: Part II

An investigation is carried out to predict the heat transfer characteristics in an irregular square porous cavity having a small isothermal heater placed at bottom left corner of cavity. The heater is of step shape with vertical right and horizontal top edges which are maintained at an isothermal temperature and right vertical surface of domain is maintained at cold temperature. The top and bottom edges of porous domain are maintained adiabatically. The governing equations are solved iteratively with the help of finite element method. Results are discussed with respect to isothermal and streamline distribution inside the porous domain.
