axial distance from the nozzle, 
nozzle width, 
distance of the nozzle from a hypothetical origin 
of the jet where the flow originates, 
co-ordinate normal to the jet center line, 
jet spread parameter, to be determined experimentally, 
it has a value of 7.7 for a turbulent free jet, 
ob, /3 (see Reference 4). 
Before going any further some quantities must be defined as 
follows: 
free stream pressure 
Static pressure within the separation bubble 
radius of the center line of the reattached jet, 
density of the fluid, 
Angular location of the point of reattachment from 
the nozzle, 
distance of the plate from the nozzle axis, 
distance of the point of attachment from the corner, 
length of the plate 
jet momentum per unit span of the nozzle. 
The equation of the reattaching streamline is given by
