Improvement and numerical simulation analysis of vortex whistle
In this paper,a new type of vortex whistle is put forward.Traditional vortex whistle and the new type vortex whistle are simulated and analyzed.The results show that the fluid velocity,turbulence intensity,turbulence kinetic energy and acoustic power density of the new type vortex whistle are significantly improved compared with traditional vortex whistle,and the acoustic power density is increased by more than 150%.
