In order to measure the flow field and mixing characteristics of the jet from rectangular nozzle

the single incline hot-wire was used in the experiments.The results show that

the strongest mixing appears radially near the interface of ambient gas and jet

and causes the maximum value of Renaults shear stress in the same position

while the turbulent intensity decreases radially.Reynolds shear stress decreases axially

while turbulent intensity increases a little

and then decreases axially.
