DYNAMICS OF TWO-PHASE FLOW IN ROCKET NOZZLES

Abstract

A critical review of the one-dimensional theory of two-phase flow was completed. A computer program to compute the properties of two-phase flow, using this theory, was devised and placed in operation. The results of the computer program and the review show that the constant-lag approximation to the one-dimensional theory is useful for engineering calculations of two-phase flow in nozzles of conventional design, not only for the Stokes flow region but also for the nonStokes flow region. Fabrication of the pressure vessels and associated mechanical devices for the two-phase flow differential nozzle apparatus was completed. The problem of manufacturing nozzles of known contour and of precisely the same throat area was solved by electroforming techniques and 11 nozzles were manufactured. The two-phase flow differential-nozzle apparatus is assembled and is undergoing calibration experiments using pure gases. (Author)
