Abstract Abstract:In order to study the pressure characteristic curve of a high frequency reversing valve and reduce pressure loss, the lattice Boltzmann method (LBM) combined with large Eddy simulation (LES) was used to simulate high-Re flow.A lattice evolution model based on LBM-LES was established for high frequency reversing valve.The valve port characteristics under different size parameters of valve were simulated.It can be concluded that the volume of oil inlet chamber and the maximum flow area have great influence on the pressure of the valve port.For a certain maximum flow area, the opening has the greatest impact on the pressure of the valve.The results show that the LBM has the advantages of accuracy and high computational efficiency and so on.Thus it can be applied to the analysis and research of complex hydraulic exciting systems.
