Abstract
This paper presents the results of an analysis of fluid flow in high pressure hydrostatic bearings and seals which can be modeled as infinitely long, closely spaced, rigid parallel plates. The flow is laminar and at low Reynolds number. The fluid is Newtonian with a viscosity which is an exponential function of temperature and pressure. The effect of the temperature variation across the fluid film is found to be extremely significant, and limits the application of the integrated adiabatic energy equation to a narrow range of the parameters.
