STUDY ON THE FLOW CHARACTERISTICS OF FREE WATER JET BASED ON HYPERBOLA FLOW LINE STRUCTURE

摘要

In the present report, the author investigated theoretically and experimentally the flow characteristics of free water jets based on hyperbola flow line structure, the conservation of momentum flux and the conservation of mass flux of free water jet. It has been developed the equation of hyperbola flow line, dynamic pressure distribution, velocity distribution and density distribution of free water jet. The theoretical equation are simple and practical, which could express the characteristics of the free water jet in any surrounding liquid medium, water and air, i.e., in all regions, initial region, main region and final region. The good agreement between the experimental and theoretical values of dynamic pressure and velocity in a free water jet is obtained.
