- Nozzles Energy loss Flow field Numerical analysis
Energy loss during the formation of high pressure water jet was investigated theoretically. Computational fluid dynamics software was used to simulate the high pressure water jet flow field produced by three kinds of nozzles, including cylindrical, conic and cosine nozzles. And the influence of the nozzle’s conic angle, inlet diameter, outlet diameter and inlet pressure on energy loss coefficient was investigated. The results show that the energy loss of the high pressure nozzle is independent on the inlet pressure but related to the angle of the nozzle, inlet diameter and the outlet diameter. With the increasing of angle and inlet diameter and the decreasing of the diameter, the energy loss coefficient will be increasing. The energy loss coefficient of the cylindrical nozzle is the largest, and the energy loss coefficient of the conical nozzle is slightly larger than that of the cosine nozzle, if they are all with the same inlet outlet diameter. This work provides theoretical basis for optimal design and efficient improving of high pressure nozzles.
