Abstract
Purpose
– The effects of a co-flow and inlet jet temperature on local entropy generation in turbulent round jets have been studied numerically. The second-order closure turbulence model has been used. The paper aims to discuss these issues.
Design/methodology/approach
– Numerical results are presented and discussed.
Findings
– The numerical results for the mean quantities, entrainment of air, mixing efficiency, generation of entropy rate and Merit number are presented and discussed.
Originality/value
– The expansion of the jet at low velocity of the co-flow and high inlet jet temperature enhances the heat transfer rate and reduces the irreversibility of the jet.
