Abstract：

The purpose of the experimental study aims at understanding the flow pattern via phase-lock loops (PLL) for wireless image transmission in a radically rotating rectangular channel. The cross-section photo show that (1) roll-cells at rotational speed 0 rpm are induced by the smoke injection flow. (2) At Ω =6rpm, the roll-cells grow up along the flow direction and the number of the roll-cells is 17. (3) At Ω =12rpm, the roll-cells grow up more quickly. The repulsion and coalescence of the roll-cells start and the roll-cells become asymmetric in the downstrcam of the vortex onset position.
