Research on Pressure Loss and Flow Field Characteristics of Hydraulic Integrated Block Flow Channel Structure Based on Fluent
Hydraulic integrated block is an important component in hydraulic system,and its flow characteristics such as pressure loss have a great impact on the performance of hydraulic system.In the technical context of 3D printing additive manufacturing,the flow field analysis of the flow channel structure was carried out to address the pressure loss in the hydraulic integrated block flow channel.Taking the pressure loss of the flow channel as an evaluation index,three key structural parameters of the flow channel were selected and L9(34)orthogonal tests were designed.Fluent software was utilized to simulate the fluid domain model with different parameter com-binations.The results of the orthogonal tests were analyzed in terms of polar deviation,and the optimal combination of the structural pa-rameters of the flow channel was obtained.The simulation results show that the cross-sectional shape of the flow channel has the greatest influence on the pressure loss.The pressure loss of the optimized flow channel structure is reduced by about 0.357 MPa,the maximum temperature is rised by 5 K,and the flow resistance is reduced compared with the common right-angle turn structure.
