Abstract: The present work is based on the analysis of wall jet developing on plane surface and at the corner of the wall. Square orifice is used to develop the wall jet on both the surfaces. Experimental and computational analysis on both plane and corner wall jet system are done. The mean velocity profiles like longitudinal and lateral, maximum velocity decay and half width growth are recorded and calculated for comparison of the corner wall jet with the plane wall jet. The mean velocity profile shows good agreement with the plane wall jet profile and also with the computational results. The decay of maximum velocity is slower in the corner wall jet when compared to plane wall jet in the longitudinal direction. The growth of half width is higher in the corner wall jet when compared to plane wall jet.
