Natural convection in Polar Enclosure / R. A. Rasih...[et al.]

Natural convection in fluid-filled, 2D cylindrical sector enclosure heated from below and cooled from above is studied numerically for a wide variety of Rayleigh number. A numerical model by using finite difference method with first order upwind was chosen for the solution of the mass, momentum and...
