针对亚燃冲压发动机燃烧室内部流动特点，结合二元稳定器试验台高速气流场燃油雾化特性试验，建立试验件三维模型并对其喷雾两相流动进行数值模拟。
Based on experimental investigation of the liquid fuel atomization in high speed airflow and the flow characteristics of ramjet combustion chamber, a three-dimensional model was established.
最后，在前面二维模拟的基础上，建立了三维气粒两相湍流流动数值模拟的数学模型，并用此模型对气粒两相气粒两相矩形射流进行数值研究。
At last, three-dimensional mathematical model of gas-particle two phase turbulence was established, and it was adopted to study the gas-particle two phase rectangular jet as well.
尤其对于未贯穿油层的水平井压裂这一增产措施来说，其流动过程也是油藏内三维流动与裂缝内二维流动相耦合的渗流过程。
Especially for the fractures which are not perforated the formation, the flow process in this system is a coupling flow about the three-dimensional reservoir and the two-dimensional fractures.
