A Theoretical Investigation of the Effect of Initial Velocity and Temperature Lag on the Flow of a Gas-Solid Suspension through a Convergent-Divergent Nozzle

Abstract

The effects of initial velocity and temperature lags between the solid particles and the gas in the high speed flow of a gas-solid mixture through a convergent-divergent nozzle are investigated. The results are interpreted physically in terms of the relative importance of heat, momentum, and kinetic energy transfer between the solid particles and the gas, and nozzle area variation.

The influences of solids loading, solids specific heat, solids density and particle diameter on the flow process are also examined.
