Authors developed a multi-fan and multi-vane type tornado simulator equipped with a moving belt to reproduce the tornado-like flow in the moving state. As results of 3D-PIV measurement, the tornado-like flow in the moving state could be reproduced as expected, and as a result of improving the operation accuracy of the device, it was clarified that this tornado simulator could reproduce the multi cell type vortex whose control was very difficult on the previous simulator. In this paper, the structure of the newly developed tornado simulator is introduced and the effect of the given swirl ratio and the moving speed of moving belt on the tornado-like flow field are reported.
