| 概要 |
In the case of rapid expansion of steam in supersonic nozzle on the assumption that the steam is perfect thermally and carolically, the phenomenon for non-equilibrium condensation in two-dimensional i...nviscid steady state flow has been studied in this paper. Also, changing of variables of the state in nozzle, onset of condensation, generation and phenomenon of condensation shock wave are investigated by the method of chracteristics when the state is changed with degree of superheat and nozzle shape. The phenomenon of onset of condensation is dependent upon shape of nozzle strongly. The smaller radius of curvature of nozzle， the configuration of onset of condensation is the more curved. The lower degree of superheat and the smaller radius of curvature of nozzle (that is, the larger drop of temperature), the generation position of condensation shock wave is the closer to the nozzle throat and the strength of condensation shock wave is the stronger.続きを見る
