AB - Numerical study of natural convection heat transfer and fluid flow in  cylindrical cavity with hot walls and cold sink is conducted. Calculations  are performed in terms of the cavity aspect ratio, the heat exchanger length  and the thermo physical properties expressed via the Prandtl number and the  Rayleigh number. Results are presented in the form of isotherms, streamlines,  average Nusselt number and average bulk temperature for a range of Rayleigh  number up to 106. It is observed that Rayleigh number and heat exchanger  length influences fluid flow and heat transfer, whereas the cavity aspect  ratio has no significant effects.
