Application of Different PDF Models for Numerical Simulation of Scramjet
Since the turbulence-combustion interaction is of great influence on complex supersonic combustion field, the different distribution of probability density function(PDF) models is studied on the basis of assumed PDF models. Considering the temperature and component fluctuations, the <i>β</i...

| description | Since the turbulence-combustion interaction is of great influence on complex supersonic combustion field, the different distribution of probability density function(PDF) models is studied on the basis of assumed PDF models. Considering the temperature and component fluctuations, the <i>β</i>-PDF and <i>δ</i>-PDF methods are used to simulate the hypersonic international flight research experimentation(HF2) direct-connect engine, and compared with the actual wind tunnel experimental results. The results show that: the prediction results of two PDF models is identical with experimental results whatever quantitate or qualitative analysis, which shows that the turbulence-combustion interaction cannot be ignored; the <i>β</i>-PDF model is better while predicting the wall pressure distribution, and has higher combustion efficiency, and can capture the turbulence-combustion interaction accurately. |
