Numerical Simulation of Vortex Formation Inside a Cavity with Two Cross Jet Flows

Simulations of steady state fluid dynamics and heat transfer in a two-dimensional flow inside a channel with main and secondary inlet flows were carried out in this work for a Reynolds number of Re = 1,562. The main cool jet was injected by a submerged inlet at the top while the secondary hot jets were injected at the vertical walls. The analysis was done by the finite element method for three different positions of the lateral entrance and three different velocities ratios of the main and secondary jets. The vortex formation and heat fluxes were analyzed and the temperature, streamline and velocity fields were obtained. The simulations have shown that is possible to control the dynamics and formation of vortices inside a channel with the variation of the secondary jet position.
