| Research Abstract |
Tornado-like flow simulator with multi-fan and multi-vane was developed to investigate effects of inlet flow condition on characteristics of tornado-like swirling upwind by PIV method. On the other hand, CFD technique, which can reproduce the flow in the tornado-like flow simulator, was developed. The results of this CFD analysis indicated that the flow around vanes is separating and the control of flow is incomplete. The improvement direction of the simulator was clarified by this result.
