    Numerical Study of Heat Transfer by Free and Forced Convection in a Ventilated Cavity

    Abstract In this paper the heat transfer by free and forced convection in a ventilated cavity is studied. The cavity is used to model a room, where a wall is receiving a uniform heat flux (like the one supplied by sun). In order to obtain the numerical results, the CFD’s software Fluent 6.3 was used and because the turbulent nature of the flow in the cavity, the k-ε turbulence model with a nonuniform grid was applied. Different values of heat flux and inlet air velocities are tested and the flow patterns and thermal fields are discussed. The heat transfer coefficients for engineering calculations are presented in nondimensional form.
