【摘要】 利用 Patankar-Spalding 方法及标准 K-ε二方程模型对椭圆型有限空间射流流场进行了数值模拟,得到了不同 Ct 数下轴心速度、壁面压力、流函数分布以及分离与再附点的位置.上述成果与试验资料对比的结果显示,二者吻合较好.更多还原

【Abstract】 Based on the Patankar-Spalding method and standard K-ε turbulence model, numerical simulation on flow field of confined coaxial jet is carried out.The sepa- ration and reattachment points as well as the velocities on central line,wall pres- sures and streamlines at different Ct number are obtained in the paper,and they a- gree well with the experimental data.更多还原
