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.
