Abstract
In the present study, a CFD simulation of a flow combined an offset jet and a wall jet (noted dual-jet) with the presence of co-flow is carried out. The effect of the intensity of the co-flow CFV (co-flow velocity) as well as its ejection angle α on the heat transfer exchanged in dual-jet flow is also performed. The present simulations are carried out for a Reynolds number Re = 15000, a nozzle-to-nozzle distance equal to 4 times the thickness of the nozzle, a co-flow velocity CFV = 10% − 40 % and a co-flow ejection angle α = 0° − 40°. The results of this computational study clearly show an intensification of the heat transfer exchanged between the flow and the wall by increasing the co-flow velocity CFV as well as its ejection angle α.
