Abstract

The results of an experimental investigation on the flow field of a dual jet which is issuing from two circular nozzles set on a common end wall and is mixed with the ambient air are described. The influence of the centre line spacing between the two nozzles over the flow field generated by them was determined. In the present work, three models with centre line spacing 2.29d, 2.66d and 3.03d were studied. It is shown that the initially individual jets merged completely at a downstream distance of ‘30d’ for all the three cases studied. Also, the magnitude of velocity profile defect decays with decrease in centre line spacing of the two jets.
