Thermal And Dynamic Study of Confluent Round Jet of Different Diameters
The interaction between two axisymmetric jets of different diameters is examined in this study in order to perform a dynamic and thermal description. The various results of the three-dimensional configurations allowed to evaluate the influence of the velocities ratio and the temperature ratio on the flow structure resulting from the interaction in convergence, merging and fully developed regions. Throughout this study the maximum heat exchange point was located for a given velocities ratio and for different temperature ratios of the two jets. In addition, we find that the velocities ratio affects the distribution of temperature particularly its thermal expansion rate. This study permitted us to propose correlations predicting both the velocities and temperature ratios of the two jets.
