Experimental and numerical investigation of multiple rectangular jets

An experimental and numerical study of the turbulent flow structure of thre e rectangular jet flows was conducted. Measurements were performed using a hot-wire anemometer having an x-type probe. Predictions were obtained using a finite-difference based computer program that solves the parabolic gover ning equations of the mean flow along with the turbulence kinetic energy an d its dissipation rate. Measurements of the streamwise mean velocity, turbu lence kinetic energy and shear stress are presented and compared with the n umerical results. Good agreement is achieved between the experimental and n umerical results. This agreement proves the ability of the mathematical mod el to predict successfully the flow field of multiple rectangular jet flows and hence can be used in documenting the detailed features and the effect of the main parameters on such important flow.
