Abstract: The present study investigates experimentally the effect of the nozzle contraction profile on the downstream development of a plane turbulent jet. The variation of the contraction profile was made by using various orifice plates with different radii. It is found that the decay and spread rates of the jet's mean velocity increase as the radius decreases. A decrease in the radius also results in a higher formation rate of the primary vortices. Moreover, the turbulence intensity is found to depend on the contraction profile.
