Abstract

In the present study, the thermal behavior of fluid in a square Enclosure with two semicircular constantis investigated numerically. The governing equations are solved by FlexPDE software, which is a simulation software base on the finite element method. The results showed that the distance between the two heaters will be a parameter affecting Heat Transfer; By reducing this distance, the Natural Convection Heat Transfer that is limited to the central part of the channel, is in the form of a symmetrical vertical column. Increasing the Hartmann number will lead to an increase in Lorentz force, a decrease in buoyancy force and consequently a decrease in temperature, a symmetrical temperature distribution and a predominance of conductive Heat Transfer. Increasing the Riley number increases the Natural Convection Heat Transfer in the form of free displacement, and by increasing the Riley number, the free-moving Heat Transfer will completely dominate the chamber.
