Influence of Built-in Filter Boundary on Flow Field in Miniaturized Hydraulic Tank

doi:10.3901/JME.2021.24.114

Abstract

Abstract: With the continuous development of hydraulic tanks in the direction of miniaturization, the filter, which accounts for a relatively large volume, has an increasingly obvious impact on the flow field in the oil tank. In order to clarify the specific influence of the boundary of the built-in filter on the flow field, the paper takes the oil return area and the oil suction area of the hydraulic tank as the research object, combined with the porous media model in the fluent module to carry out the finite element numerical simulation of the filter. Explore the influence of the filter installation position and boundary range on the internal flow field of the fuel tank, and compare the internal flow field velocity, energy dissipation and particle sedimentation under different boundaries.At the same time, the correctness of the filter model and simulation method and the accuracy of the simulation results are verified through theoretical calculations and PIV visualization experiments. Finally, the evaluation index of the influence of the physical boundary on the flow field is obtained. Based on the index parameters, the law of the influence of the filter boundary on the internal flow field is revealed, and the basis for selecting a better boundary range is given. The influence law of the filter boundary on the flow field in the oil tank is summarized, and a reference for the miniaturization design of the hydraulic tank is provided.
