Natural convection is modeled in an infinitely long horizontal circular cylinder which is heated from below and cooled from above. This combination of thermal boundary conditions produces an unstable flow which must be modeled with a transient algorithm. The buoyancy-driven flow is studied for three different values of the Rayleigh number, Ra = 5(10{sup 3}), 5(10{sup 4}), and 5(10{sup 5}). The problem is modeled and solved using the finite element based code ANSYS/FLOTRAN{trademark} computational fluid dynamics (CFD) program. Results include temperature and streamline contours.
