旋风式燃气过滤器的冷流实验和内流场模拟

Experimental and numerical simulation on a cyclone filter for gas generator

为了考察某导弹系统燃气发生器的旋风式燃气过滤器的除尘特性,对其进行了冷流实验研究,对除尘效率进行了模拟测量,并应用多流体模型的IPSA算法对其内流场进行了三维两相的数值模拟。计算结果与实验结果较符合,计算得到的分离界限粒径为2μm～3μm。

To investigate the performance of a cyclone filter for hot gas generator of a missile system, the cold-flow experimental and numerical simulation were given. The IPSA algorithm based on multi-fluid model was used for the numerical simulation of three-dimensional two-phase flow in the cyclone filter. The calculations agree well with the experimental data, the separation limited diameter from calculation is about 2μm-3μm.
