| Abstract: |
| 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. |
