- Abstract:
- A three-dimensional linear interpolation method is developed for the exchange of CSD/CFD coupling calculation data to execute numerical simulation of air/thermal/liquid-structure coupling for a partial admission turbine in liquid rocket engine. The results show that the developed three- dimensional linear interpolation program relies on grid type weakly, has the characteristics of simple calculation and less calculated quantity, and can meet the requirements of coupling calculation. The results of the coupling simulation show that a serious shock wave is generated at inlet of turbine rotor, which makes the blade load distribution asymmetrical which has an important impact on the turbine rotor. The coupling calculation and analysis
