    Abstract

    This paper provides an overview of hydraulic fluid impact on the inlet condition and cavitation potential. A clear understanding of physical properties is vital to properly evaluate their effect on lubrication and cavitation. Proper hydraulic system design is critical for optimal operation and to eliminate cavitation as a root cause of wear. The importance of proper inlet conditions on hydraulic system performance is reviewed. The effect of physical properties, including vapor pressure, viscosity, density and bulk modulus on cavitation, as well as the idea of a pump-specific critical cavitation number is also discussed.

    Keywords:

    cavitation, cavitation number, hydraulic fluid, density, bulk modulus, compressibility
