Numerical Simulation of an Open Cavity with Heating in the Bottom Wall
This work presents the numerical simulation of heat transfer and fluid dynamic in steady state of a two-dimensional Cartesian flow inside a cavity with one inflow and one outflow for Re = 100 and 1,000. The domain of the simulation consists in a rectangular section with two different aspect ratios. Three different lengths of the heater at the bottom wall were analyzed. The governing equations of continuity, momentum and energy for incompressible flow were solved by the finite element method. The velocity fields, isotherms, streamlines and vortex formation were studied. The simulation indicates that is possible to control the dynamic and vortex formation inside the cavity due to the variation of the length of the heater.
