Mean Flow Characteristics of a Three-Dimensional Wall Jet on Concave Surface in the Radial Decay Region
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 12
Abstract
This paper presents the mean flow characteristics of a three-dimensional wall jet on concave surface. The velocity measurements were taken up to an axial distance of 60 times the diameter of the orifice selected in the present work. The mean flow properties considered in the present investigation are the mean velocity profiles, maximum velocity decay and the growth of half width in the normal direction to the plane surface and concave curved wall. It is observed that the mean velocity profiles of the wall exhibit similarity both on the plane surface and concave curved surface in the longitudinal direction. It is shown that the decay of the maximum velocity is slower on concave surface when compared with the decay on plane surface. It is also found that the growth of half width is higher on plane surface compared the growth on the concave curved surface. The velocity profiles are similar in the spanwise direction and no effect of curvature is felt.
