Numerical Simulation of Gas-solid Erosion on the Inner Wall of V-shaped Regulating Ball Valve Cover
Combined with a custom erosion model,it is possible to more accurately predict the erosion and location in the pipeline,Combined with the characteristics of the flow field in the bonnet and the damage of the bonnet,the erosion process was studied by numerical simulation.On the basis of the flow field simulation,the erosion and wear of the inner wall of the valve cover under the rotation angle of the valve ball of 30°,50° and 70° were further explored,and the erosion and wear of the bonnet wall were simulated and analyzed with the help of Fluent.Finally,the optimal channel size was calculated and simulated by changing the channel width at the inlet of the valve seat,and the inner wall of the valve cover was reinforced to minimize the influence of medium erosion at the valve wall.
