Abstract

A technique for determining the total mechanical impulse and the reactive force of an incipient non-stationary gas flow, on evidence derived from interference cine films, allows a reconstructive tomographic problem of reconstructing velocity and pressure fields in such objects to be formulated. This concept allows the distribution of velocity and pressure fields in such flows to be determined. The potentialities of the concept have been taken advantage of in estimating velocity and pressure fields arising on ignition of a premixed gas by a heated point body.
