LAMINAR NATURAL CONVECTION STUDY IN A QUADRANTAL CAVITY USING HEATER ON ADJACENT WALLS

Abstract
Numerical analysis of laminar natural convection in a quadrantal cavity filled with water having variable length heaters attached on the adjacent walls have been made to examine heat and fluid flow. Numerical solutions are obtained using a commercial computational fluid dynamics package, FLUENT, using the finite volume method. Effects of the Rayleigh number, Ra, on the Nusselt number, Nu, as well as velocity and temperature fields are investigated for the range of Ra from 103 to 107. Computations were carried out for the non-dimensional heater lengths on the vertical wall (m=0.2, 0.4 and 0.6) and horizontal wall (n=0.2, 0.4 and 0.6). It is observed that both flow and temperature fields are affected with the changing of location of heater and length of heater as well as Rayleigh number.
