Experimental study on shape of sudden lateral enlargement and vertical drop for radial gate slot of deep outlet for Altash Water Control Project
摘要
Abstract
Altash Water Control Project is the largest leading reservoir within Yarkant River Basin,for which the type of sudden lateral enlargement and vertical drop is adopted for the slot of the radial working gate.The operation water head of the working gate is high with large flow rate,while lager risk from cavitation and cavitation erosion is there in the area of the slot.Taking the study and verification of the hydraulic and cavitation characteristics of the shape of sudden lateral enlargement and vertical drop for the slot of the radial working gate for the No.1 deep outlet of Altash Water Control Project as the objective,the optimized flow patterns within the area of the gate with the shape of sudden lateral enlargement and vertical drop are compared with three schemes.The experiment result shows that the water-wing intensity is effectively reduced after adjusting the diffusion angle for the diffusion section of the side-wall to 1.273 °,and then the hydrodynamic pressure and the flow cavitation characteristics at the slot section are obviously improved.The shape of sudden lateral enlargement and vertical drop for gate slot with better flow pattern and anti-cavitation characteristics proposed herein provides some experiences and references for the design of the gate shape for the radial working gate of deep outlet with high water head and large flow rate in the days to come.关键词
