摘要：本文基于超临界流体的特性，在一维定常可压缩流体流动的基础上，结合对流传热建立了超临界溶液快速膨胀过程（RESS）的计算模型。该模型将RESS过程喷喷内的流动分为等熵节流和一维定常可压缩管流两个部分。利用该模型可计算RESS过程中喷嘴内部的流动，为研究RESS过程提供基础．
The fluid flow in the nozzle is modeled numerically based on one-dimensional compressible time-independent flow with considering the characteristic of supercritical fiuids and convection heat transfer by taking the flow through nozzle as an isentropic throttle following a one-dimensional flow with heat exchange and friction in the capillary. The model can describe the heat effect during the fluid expansion in the nozzle and can be used to research the RESS process.
