Numerical Simulation of Jet Flow Led by Different Central Body Locations
To predict the operation effect of a cavitation nozzle with inner central body, geometrical model and numerical model are established Flow fields led by different axial locations of central body are analyzed contrastively. Total pressure, velocity and turbulent ldnetic energy are three focused parameters in the study. It is proved that different kinds of central bodies have remarkable influence on flow energy and operation effect. An optimal geometrical configuration is finally determined The advantages and disadvantages of the nozzle type are also remarked. The study here provides helpful references for further simulation with reasonable and validated cavitation model and experiment research with advanced flow visualization tools.
