Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.
Steady laminar natural convection heat transfer inside airfilled
square cavities cooled at one side and partially heated at
the opposite side, is studied numerically. A computational code
based on SIMPLE-C algorithm is used for the solution of the
mass, momentum, and energy transfer equations. Simulations
are performed for different values of the dimensionless size and
location of the heater, and the Rayleigh number, whose effects
on the temperature and velocity fields, and on the heat transfer
rate across the cavity, are analyzed and discussed.
