摘　　要：The chute aerators separate the flow from the chute bottom,and the violent turbulence is generated after the flow impacts the bottom.Although the chute aerators were widely investigated experimentally,the air concentration distribution of the lower jet in the impact zone remains to be explored systematically.In the impact zone,it is observed that a portion of the air stays in the rollers instead of traveling with the flow,decreasing the air transportation capacity.Based on extensive tests,a comprehensive formula is developed to compute the air concentration distribution in the impact zone,with results in good agreement with the model tests.
