The flow field in the herringbone grooved bearing was simulated by computational fluid dynamics software FLUENT, the comparison of static characteristics was made between the modal considering effect of viscosity-temperature or not. Temperature field distribution on the surface of herringbone grooved bearing was product in the case of different structure parameters (including spiral angle, groove...
Three dimensional fluid flow between coalescence separator plates with different shapes have been numerically simulated by the standard K-ε turbulence model in Fluent CFD. The separation characteristics of different separators have been compared. The simulated results show that the corrugated plates and the trapezoidal plates both have relatively high separation efficiency and good effects on flow...
The paper introduces a kind of special emulsification device to apply in the coal mine. This special emulsifying device uses damping board to make water and emulsible oil turbulence increasing and vortex of different size when they flow through this device. With strong pulsation of the vortex, emulsible oil and water are diffused, mixed and transfered to all directions thus they are mixed adequately...
