| Abstract: | In order to
understand the effects of supersonic jet impingement, static tests are
conducted in a small-scale rocket motor loaded with a typical nitramine
propellant to produce a nozzle exit Mach number of 3. This jet is made to
impinge on a plate aligned vertically to the nozzle axis. The distance between
the nozzle exit and the plate is varied from 2 to 6 times the nozzle exit
diameter. The pressure rise due to jet impingement on the plate has been
measured using pressure transducers located at ten different radial locations.
The pressure - time data are analyzed to get an insight into the flow field
upstream of the plate. The maximum pressure exerted on the plate is about
20-30% of the maximum pressure generated in the combustion chamber. Ten static
tests are carried out to obtain the effects of nozzle divergence angle, axial
distance between the nozzle exit and the plate and the chamber stagnation
pressure on the flow field. |
