Abstract :An investigation of the jet development on the flat plate and the temperature effectiveness on the adiabatic surface in three dimensional,incompressible,turbulent wall jets issuing from rectangular nozzles was undertaken.Experimental results of pertinent mean flow properties such as maximum velocity decay,growth of half-velocity width,growth of equi-velocity lines and temperature effectivenes are reported by changing the nozzle configuration,or the Aspect ratio of the rectangular slot,theinitial velocity,and the temperature of the initial flow. The flow fields of such jets are found to be characterized by three distinct regions in the maximum velocity decay.The flow patterns in the region far downstream agree well with other reports,velocity defects in the neighborhood of the potential core region,however,are pointed out.Distribution of the temperature effectiveness in the region far downstream is found to be arranged by a simple power law.
