Abstract

In this paper we study the rate of climb, thermal expansion and buoyancy force with free convection considering it as an incompressible fluid and steady. Thermal analysis is given for different values of the Grashof number given a linear approximation of temperature. For this, the dimensional finite difference method is used, and dynamic Navier-Stokes equation is solved in the Boussinesq approximation, in order to get the particle velocity of fluid as a function of height and radius of the thermal.
