%X Considering that the viscosity of the hydraulic oil will change
accordingly when the temperature and pressure vary, the flow rate equation and
leakage rate equation of the annular spiral flow in Hydraulic Rotary Actuator
are derived based on continuity equation, N-S equation and energy equation.
Using the CFD simulation software ``Fluent'', the flow field and the leakage
law of the internal annular spiral flow are simulated. Comparing the simulation
results with the theoretical calculation of the flowing annular spiral flow, the
theoretical analysis is verified, which may provide a
theoretical basis for studies of internal leakage and volume depletion in Hydraulic
Rotary Actuator.
