Injection of Liquid into the Strut Shadow at Supersonic
Velocities 931455
Presented are the results of the experimental investigation into the geometric
characteristics of liquid fuel (kerosene) plume in pylon near wake: the height
of “liquid foot”, the upper and bottom boundaries, the plume cross section and
droplet diameter depending on the distance between the liquid fuel injection
orifice and pylon base, the pylon shape, Mach number, fluid viscosity, ratios of
dynamic pressure of jet to dynamic pressure of flow, etc.
The experimental data were obtained by processing Tepler and conventional
photographs made by laser “cutter” for plume cross- sections and method of the
integrating diaphragm for droplet diameters under free stream Mach numbers 2,5-4
and T =300 K.
