摘要
分析了射流夹带流的特性,建立了柱坐标系及控制体,并利用流体的连续性方程给出了夹带流沿母线的速度公式,同时给出了夹带流流量的理论解,并用数值模拟的方法比较分析了理论解和实验数据,结果表明两者具有良好的一致性.
This paper analyzed the characteristics of jet entrainment flow formed by a circular jet nozzle,established a cylindrical co-ordinate system and a control body,and proposed a formula on the velocity of entrainment flow perpendicular to the generatrix and a theoretical formula of entrainment flow by implementing the continuity equation of fluid dynamics.Furthermore,using the data from previous experiments to compare with the theoretical results,the result shows that this formula is in good consistency with the experimental results.
