摘要:

ＣＦＤ／Ｎｏｚｚｌｅ软件包是一套专门的二维轴对称跨音速喷管流场计算机辅助设计分析工具。它采用高度集成化的操作环境，将网格生成、数值计算、图形显示全部过程集于一体。具有西文环境下的全中文用户界面，操作环境同时提供详尽的彩色图文方式下的中文提示。数值方法稳健，兼具源程序开放与编译连接自动化特点。叙述了ＣＦＤ／Ｎｏｚｚｌｅ软件包设计思想和实现方式，并给出了流场计算、参数分析、功能扩充几方面的应用实例。

Abstract:

As a set of specific CAD analysis tool for two-dimentional axisymmetric transonicnozzle flow simulation, the CFD/Nozzle software contains a highly integrated operation environmentthat can join the procedure of code preparation, grid generation, numerical computation and graphoutput together to form an interrelated unity. Operation environment can also provide detail helpinformation that include colorful diagram and documents. The source cede of computer program iseditable, and can be compiled or linked automatically. Present in the paper is the CFD/Nozzle softwaredesign consideration, related technical route and some results of its application.
