Abstract

Inverse installation method of large-scale storage tank has such advantages as less investment, high efficiency, no aloft work, et al, but instability problem may occur during the promotion process in the case of a gale. To evaluate the wind load encountering a gale during the stage of construction, flow field around tank was studied by CFD. Based on simplification and model building of flip tank, the flow fields were simulated for different inlet wind velocity. Combined with the contract of the velocity field inside and outside of tank, the characteristics of the pressure distribution on the tank wall were discussed. The horizontal and vertical wind load on tank wall was calculated and the law of wind load affected by inlet wind velocity was analyzed. The result of the wind load for different inlet wind velocity provided the basis of construction stress analysis of hydraulic lifting equipment for flip-tank.
