Abstract

A mathematical model is presented to describe distribution of dimensions for particles of liquid-dropping phase in outlet flow of small-thrust liquid-propellant engine. Main problem attached to selection of distribution function consists in strong dependency for density of outlet flow from particle outlet angle. It is offered to solve this problem by means of replacement a local distribution function defined along a separate line of flow with some distribution function for a whole ensemble of particles discharged with the engine. It is possible to use a simple power function as a distribution function in such a case.
