DYNAMICS OF TWO-PHASE FLOW IN ROCKET NOZZLES.

Abstract

An experimental and theoretical investigation was made of the axial and radial velocity lag of a dispersed solid phase in accelerating gases. The program objective is to generate basic information and nozzle design criteria for twophase flow resulting from the combustion of metallized solid propellants. Development continued of the experimental apparatus to measure particle drag coefficients in the regimes of particle Mach numbers 2 and Reynolds numbers 1000. Fabrication of the particle acceleration section is near completion and the design of the associated electronic equipment was completed. More refined calculations have verified the feasibility of tracking a small particle by detecting, photoelectrically, the light reflected from its surface as it moves along a beam of intense light. Design of a tracking section utilizing this tracking technique is proceeding. Pressure distribution measurements were continued on the two-dimensional nozzle with pure gas flow in preparation for measurements with gas-particle flow. (Author)
