内容記述 | In this paper, by means of numerical experiment, the transient response of the flow in the vortex diode and the steady flow field in the vortex chamber are investigated in detail. The flow in the chamber is regarded as an unsteady, three-dimensional, incompressible and viscous flow. The primitive Navier-Stokes equations are solved by using p-u method. The calculated vortex diode consists of four tangential nozzles, a square vortex chamber and an exit nozzle. The results obtained can be summaried as follows : 1) In the transient reverse flow, two distinct stages are recognized as known in the physical experiment. The significant pressure drop in the chamber occurs at the second stage when the rotating flow is accelerated. 2) In the steady reverse flow, the radial velocity in the end wall boundary layers is larger than that at midplane. Therefore, the most fluid particles flows out of the chamber through the end wall region. 3) The diode ratio, which has never been known theoreticaly, can be predicted by calculating the forward flow field too. | |||||||||||||||||
