It can be seen from Equation 2 that the jet velocity u(s,y) 
is maximum at its center-line and is

Next, it can be deduced from Equations 2 and 3 that the jet 
velocity u(s,y) drops to 0.1814 umax at a distance equal to 
the half width of the jet from its center line. The centrifugal 
acceleration distribution in the jet can be derived from Equation 
2 and is given by

Again it is evident from Equation 4 that the centrifugal acceleration, 
u(s,y) is maximum at the jet center line and is

umax = do (sts )r (6) 
The acceleration drops sharply to approximately 0.0327 umax 
at the jet half-width points. 
The typical velocity and acceleration for the reattaching 
jets are shown in Figure 13. Because of the nature of lateral 
acceleration on the jet, the oil particles are distributed 
over the entire cross-section. Such a distribution of centrifugal 
acceleration affects the separating capability of a separator 
with this configuration. 
The mixture jet velocity and hence its centrifugal acceleration 
distribution can be improved by modified designs. One such 
design is shown in Figure 14. The device uses a splitter located 
at the nozzle center-line to divide the mixture jet into two 
sub-jets which flow along the curved walls as shown. The mixture 
jets flowing through the device will have velocity distribution 
as shown in the figure, i.e., from a maximum near the curved
