摘要

The off-design performance characteristics of two-phase nozzles were investigated and the impact of heat transfer enhancement between the liquid droplets and the suspending gas on the nozzle performance were examined. The problems associated with the integration of two-phase nozzles with the potential heat sources were reviewed. An experimental program formulated to verify the predicted two-phase performance is outlined. Typical two-phase nozzle performance maps are presented to show the off-design total mass flow rate and the nozzle efficiency, as a function of loading ratio, inlet pressure and temperature, and exit pressure. The effects of droplet size and secondary injection of hot liquid as well as the effect of using an exponential instead of a linear axial pressure profile on the nozzle performance are discussed. The effects of droplet size and local gas velocity on the level of flow disturbance (shock) in a two-phase nozzle flow are also examined.
