Entropy Generation Minimization Concept Evaluating Mixing Efficiency Through, Variable Density, Isothermal, Free Turbulent Jet

摘要

This paper is devoted to the numerical and theoretical study of axisymmetric variable density jet discharging into a co-flowing stream. The results reveal that k-ε models give satisfactory agreement with experimental data. The results show also that entropy generation due to mass transfer is very higher than that corresponds to fluid friction. In addition, it was found that Entropy Generation Minimization concept can be used as an indicator to evaluate mixing efficiency and mixedness.
