Abstract
An analytical procedure of supersonic nozzle flows of gas–particle mixtures is described for the case where a nozzle configuration has previously been prescribed. Thereby, some numerical examples concerning the flow properties of gas-phase and particle-phase are illustrated.
There are two equations for determining the gas velocity. One includes a term of the variational cross-sectional area along the whole nozzle length. The other includes a term of the pressure profile, instead of the term of the foregoing area. At the present situation where the supersonic nozzle flows are treated for a given nozzle geometry, the former equation is employed upstream and downstream of the transonic region and the latter is utilized in the transonic region. The numerical perturbation between the above two equations is examined and discussed from a practical point of view.
