- Abstract
To study the energy loss of water-based TiC nanofluids flowing in hydraulic pipelines, a “two-step method” was used to prepare water-based TiC nanofluids that met the flow characteristics of hydraulic media. Using No. 32 hydraulic oil as a reference, the simulation analysis of the hydraulic pipeline flow field was carried out by using CFD, and the experimental analyses of the pressure drop and temperature difference of the hydraulic pipeline flow were carried out. The research results show that when the hydraulic medium flows in the L-shaped pipeline and the T-shaped pipeline, with the increase of the inlet pressure, the pressure drop of the hydraulic medium increases and the temperature difference decreases; the pressure drop of water-based TiC nanofluids hydraulic medium is smaller than No. 32 hydraulic oil, and the temperature difference is greater than that of No.32 hydraulic oil. The numerical simulation and experimental results are basically consistent. So the water-based TiC nanofluids can meet the performance requirement of hydraulic transmission medium.
