Abstract : The report consists of two parts. Part One is concerned principally with the physics of the interaction of droplets or solid particles with a gas stream in the presence of heat and mass exchange and with the influence of these factors on the characteristics of the engine. The problems of liquid injection (the basic parameters of the fuel-supply system and methods of measurement) are considered, dimensionless relationships are cited for spray spectra in a supersonic stream, and ranges and vaporizabilities in fuel sprays are determined. Part Two describes the process of turbulent mixing for various boundary conditions with or without evolution of heat on the basis of a consistent method of calculation; the relationships obtained can be used to calculate turbulent mixing in the cases of free jet, jet at a wall, and a jet in a nozzle.
