Abstract
In the present work, we analyze the laminar steady-state fluid dynamics, heat and mass transfer in a two-dimensional open cavity for the decomposition of a substance. The numerical study is carried out for Reynolds numbers of 10, 25 and 50 with a Schmidt number of 425. A hot plate is provided at the bottom of the cavity which generates the thermal decomposition of the substance. In order to investigate the effect of the length of the plate two different plate sizes are considered. The governing equations of continuity, momentum, mass transport and energy for incompressible flow are solved by the finite element method combined with an operator-splitting scheme. We calculate the temperature field, the streamlines, the velocity and the concentration field and analyze the velocity, concentration and temperature profiles as a function of the transversal position. We find that the Reynolds number plays a major role in the mass transport and the thermal behavior of the flow inside the cavity.
