Investigation of the physics of mixing enhancement

overexpanded.jpg (31756 bytes)

Through an exploratory grant from the National Science Foundation, we are investigating the  fundamental processes that cause the mixing enhancement in MESPI and JSE.    We will focus on what happens inside and outside a converging-diverging nozzle operated in overexpanded mode.    The facility drawn above will allow some unique observations of the internal and external flow phenomena.
