Influence of thermo-physical properties of hydraulic fluid on axial piston pump dynamics: An experimental validation and numerical study with leakage flows and power losses

This work presents a comprehensive mathematical model to predict the thermal behavior and performance of axial piston pumps (APPs). The model simulates piston motion, flow and pressure dynamics, power losses across critical interfaces, and temperature rise due to viscous frictional heating. A novel approach of the work is the integration of temperature and pressure derived from the above simulatio…
