In the previous report, Experimental results of the jet development and the temperature effectiveness on the adiabatic flat surface in the three-dimensional wall jet flow are discussed. This paper deals with a continuous experimental study in which the flow and the temperature fields on the adiabatic flat surface in the threedimensional, incompressible, turbulent wall jet flow issuing from two square nozzles are discussed. Maximum velocity decays and growthes of half-velocity widthes on both central lines of the nozzle and the flow, growth of equi-velocity lines, and distribution of the temperature effectiveness are reported with varying the central distance of the nozzles, the injection velocity and the temperature of the injection jet. The flow fields of such jets are found to be characterized by two distinct regions ; One shows two peaks flow and the other shows one peak flow which is observed at far downstream. The flow patterns as well as the temperature distribution differ at both regions. Transition points between these two situations are much depending on the central distance of the nozzles, but less on the initial velocity. Flow visualization, with using oil-film technique, has been tried to observe and grasp the induced flow situation (or entrainment of surrounding fluid) along the wall, and reasonable explanation for the velocity defects in the neighbourhood of the potential core regions could be obtained by its photographs. |
