The effects of varying Reynolds Number, Prandtl number, Froude number, and Euler number on the temperature and velocity was investigated. In the study, the top surface of a vertical cylindrical container was cooled, the bottom surface heated and the vertical cylindrical walls were considered as being adiabatic. The non-linear governing equations subject to Boussinesq approximation were solved using finite difference method. Results were analysed and presented in graphs to understand the fluid flow and temperature profiles at various locations in the enclosure. Results indicated that buoyancy forces due to temperature difference between the bottom and top of the cylinder are important in determining the velocity of air in the enclosure.

The governing equations describing the flow along with the boundary conditions are solved by Finite Difference Method using the MATLAB computer generated program. A numerical investigation are performed to estimate the effects of varying Darcy number, radiation, magnetic, and suction parameters on fluid velocity and temperature on MHD free convective flow. The effects of changing these values on Temperature distribution and velocity flow are shown in the graphical and tabular forms. We have presented the non-dimensional velocity u and temperature for several values of magnetic parameter M 2 , Radiation parameter R, Darcy number Da, Prandtl number Pr and Suction parameter S. It was discovered that the velocity u increase with decrease in Suction parameter S and magnetic parameter M 2 and increase with increase Darcy number. For temperature, it is also found that the temperature increases with decrease in Prandtl number Pr and increases with increase in Radiation parameter R and Suction parameter S.
