A new hydraulic transformer (named NHT) prototype has been designed and tested by Zhejiang University in China. The results show that the HT can realize the function of transforming pressure, but its parameters such as efficiency and noise should be improved further. To help optimizing it, CFD-simulation using commercial software FLUENT is introduced. And the fluid field inside this hydraulic component can be theoretically analyzed. The velocity field and pressure distributing at different places such as the oil gap between the cylinder block and the valve plate, and between the valve plate and the end cap, or inside the cylinder chamber are founded. And the flow fields were analyzed in different rotate speeds and control angles. Besides the flow field was discussed under different grid cell numbers. The conclusions contribute to the understanding of the flow conditions inside the NHT and thereby supply dependences foroptimization on the NHT.
