The 3D FEM Simulating Study on High Pressure Swirling Jets

研究了叶轮导引射流喷嘴内部流场的流动特性 ,编制了流体的三维有限元数值模拟软件 ,介绍了此软件的编制原理及其构成 ,并通过对一实例的计算揭示了喷嘴内流的一些特点。

For studying the flow attribute in propeller guided nozzle,the writers compile a 3D FEM simulating software.This paper introduce the principle and the structue of this software.After the computing of a example,some characteristics of the inner flow were obtained.
