Numerical Simulation of Oil Chamber's Performance at Different Speeds

A two-dimensional model is established for studying the shear rate's effect on lubricating oil of Newtonian fluid and Non-Newtonian fluid.Oil film's work properties of large size and high-speed hydrostatic support system are simulated by the finite volume method.Results show that the viscosity of liquid changes with the increase of the speed,and the shear thinning non-Newtonian fluid has a better work property.These are important to the design of the hydrostatic support system with large size and high-speed and to the investigation of oil film's work properties.
