A new concept of a liquid wall divertor using fluid mixing effect is suggested. It is composed of two flows. One is main flow and the other is assistant inclined flow.

It is confirmed that by mixing effect of the assistant flow toward the main flow, the heated surface of main flow is dragged into the inside of the main flow and that, the surface flow velocity increases as that of assistant flow becomes larger. In addition, the larger velocity of assistant flow and faster main flow is effective to decrease the temperature of the surface flow.
