A combined simulation model and data methodology for erosion rate prediction of underwater throttle valve
摘要
Abstract
In order to solve the problem of inaccurate erosion rate prediction due to the interaction between the throttle valve and the fluid containing solid sand particles in the underwater production system during the erosion process,a method combining numerical simulation and experimental data was proposed.Firstly,the change characteristics of the surface profile of the test sample are obtained through erosion experiments,and finite element models under different erosion times are established;Then,in the ANSYS FLUENT simulation environment,combining the finite element model,two-phase flow model,and erosion model,simulation experiments were conducted to obtain the erosion rates of underwater throttle valves at different time scales and surface topography,and the erosion rates and flow field pressures of underwater throttle valves were analyzed;Finally,using RBF neural network to perform function fitting on the erosion simulation data of underwater throttle valves,a prediction model for erosion rate of underwater throttle valves is established that integrates the dynamic evolution of erosion degradation.The results show that the accuracy of the established prediction model for erosion rate of underwater throttle valves based on numerical models and data is improved compared to traditional erosion rate prediction models.关键词
