TALK=T;RUN(1,1) DISPLAY The problem considered is the submerged free heated turbulent round jet in stagnant surroundings, as described under PHOENICS Library cases 153-155. The calculations are started at the jet discharge, and the parabolic marching integration is carried out until both the mean flow and turbulence profiles become self similar. The calculations are made with 30 grid cells across the jet and a forward step size of 5% (DZW1) of the local jet width. The y- extent of the grid is set equal to the diameter at z = 0, thereafter being caused to increase linearly with downstream distance so as to accommodate the radial spread of the jet. For testing purposes the number of forward steps is set equal to 20, but for the attainment of self-similarity, it is recommended that NZ is set equal to 210, so that the marching integration is terminated at an axial distance of about 50 diameters from the jet discharge.
