摘要：

It is known in the previous researches that the swirl flow in circular pipe causes the temperature separation. Recently, it is shown that the temperature separation occurs in a chamber composed by cylindrical vortex chamber, tangential pipe, the central rod and discharge collector. In this device, high and low temperature regions occur in a cavity on the circumference of the chamber and center in vortex chamber, respectively. The highest temperature was observed in the bottom of the cavity. Therefore, it is expected that this device can be used as a heat source in the engineering field. In recent researches, the mechanism of temperature separation in the vortex chamber has been investigated experimentally and numerically by some researchers. However, there are few researches for the effect of configuration and position of the cavity on the temperature separation. In the present study, the effects of configuration of vortex chamber including a cavity and cavity position on temperature separation in the vortex chamber were investigated experimentally.
