A model of oil with entrained air content is developed which considers fluid compression and the subsequent dissolving of mixed entrained air. According to the model the mixed entrained air affects the "gross" bulk modulus below some critical pressure, but has no effect above this value due to ...
air polytropic course equation,a theoretical model of dynamic bulk modulus for an aerated hydraulic fluid is derived.The effects of system pressure,air fraction,and temperature on bulk modulus are investigated using the controlled variable method.The results show that the dynamic bulk modulus of the ...
Bulk Modulus of Air Content Oil in a Hydraulic Cylinder A model of oil with entrained air content is developed which considers fluid compression and the subsequent dissolving of mixed entrained air. According to... R Jian,R Burton - Asme International Mechanical Engineering Congress & Exposition ...
i.e., the dynamic process of air release and dissolution is disregarded. Consequently, they cannot accurately describe the dynamic change process of the bulk modulus. Meanwhile, dynamic models consider the time effect of air components in aerated hydraulic fluids with pressure change; ...
bulk modulus n (General Physics) a coefficient of elasticity of a substance equal to minus the ratio of the applied stress (p) to the resulting fractional change in volume (dV/V) in a specified reference state (dV/Vis thebulk strain). Symbol:K ...
The bulk modulus and density of each fluid type, that is, oil, water, and gas, at reservoir conditions are required to calculate the undrained bulk and shear moduli, as well as the fluid-saturated density of the reservoir. The fluid parameters can be determined experimentally in the laboratory...
When dealing with substances that are in a solid-state, such as ice, you can use a bulk modulus of elasticity. This gives a good approximation of whether or not you will be able to damage or crack the ice. If it has a high bulk modulus of elasticity, then it is unlikely that you ...
