Occurrence characteristics of gaseous cavitation in oil shear flow

چکیده
In the present study, a decompression experiment involving two rotating concentric cylinders with hydraulic oil between clearances was performed. The dependency of occurrence condition gaseous cavitation in investigated not only based on rotation speed, which corresponds to shear strength flow, but also pressure history flow. As result, characteristics were found be divided into regions separation: equilibrium separation is constant respect occurs under lower conditions, and non-equilibrium decreases according increase higher conditions. addition, boundary speed separations formulated.

Numerical Simulation of Cavitation in Mixed Flow Pump
The purpose of this study is to investigate the performance and three-dimensional behavior of the flow in a mixed flow pump and the way cavitation phenomenon is affected by different parameters such as fluid temperature, pump speed and flow rate. Computational fluid dynamic software FLUENT 6.3 was utilized to simulate the whole flow field of the pump. RNG k-ε model combined with standard wall f...
متن کاملInvestigation of the Flow and Cavitation in a Butterfly Valve
Since knowledge on hydrodynamic torque of a butterfly valve is very important for butterfly valve design, its hydrodynamic torque is investigated in this paper. In reality, the investigation of the loss coefficient and torque from some experiments will take a long time and a lot of money. This paper presents a statistical study of the flow past the butterfly valve in a static analysis using com...
متن کاملSome characteristics of thin shear layers in homogeneous turbulent flow.
Tomographic particle image velocimetry measurements of homogeneous isotropic turbulence that have been made in a large mixing tank facility at Cambridge are analysed in order to characterize thin highly sheared regions that have been observed. The results indicate that such regions coincide with regions of high enstrophy, dissipation and stretching. Large velocity jumps are observed across the ...
متن کاملShear Driven Micro-Flows of Gaseous Mixtures
A mesoscale kinetic-type approach is proposed to solve shear driven micro flows of binary gas mixtures in MEMS. The coupled linear integro-differential equations, which formally describe the flow, are solved using the discrete velocity method. The complicated collision integral term is approximated by the McCormack model. The proposed approach is applied in one and two dimensions, solving the C...
متن کاملGeology Creep cavitation bands control porosity and fluid flow in lower crustal shear zones
9 Shear zones channelize fluid flow in the Earth’s crust. However, little is known about 10 deep crustal fluid migration and how fluids are channelized and distributed in a deforming lower 11 crustal shear zone. This study investigates the deformation mechanisms, fluid-rock interaction 12 and development of porosity in a monzonite ultramylonite from Lofoten, northern Norway. The 13 rock was def...
