Özet:

The present work is interested in the mathematical and numerical modeling of the effects of different parameters such as the angle of the cone, the length of the cone, the hot source radius, and the hot source length on thermal plume flow in interaction with its surrounding. The behavior of the guided thermal plume flow can give us more knowledge about the control parameters of different applications relevant to the environment and industry. This study investigates the thermal plume in interaction with its surrounding environment. To determine the control parameters that influence this flow we must study at the beginning mathematically and numerically the studied flow thru a natural convection flow generated by a circular hot source at the entrance of a vertical cone (Figure 1). In this work, the flow is natural convection, turbulent, steady, two-dimensional, incompressible flow. Numerical results are obtained using CFD analysis based on mathematical modeling of the flow and ANSYS-FLUENT software. The introduction of the hot source with a different radius causes an important change in the flow structure. The profiles show a very strong gradient in the temperature in the zone near the plume source for a specific cone angle. The comparison of different profiles indicates the optimized control parameters of the flow.
