Heat & fluid flow conservation equations of carburant liquid droplet are solved by a semi-implicit method the Volume Of Fluid ( VOF ) scheme. A new technique radius regression estimation based on Piece-wise Linear Interface Calculation PLIC is developed. Numerical computation performed for stagnant droplets in evaporation natural convection (which takes into consideration buoyancy forces) and a...

We present a novel interface-capturing scheme, THINC-scaling, to unify the VOF (volume of fluid) and level set methods, which have been developed as two different approaches widely used in various applications. The key success is maintain high-quality THINC reconstruction function using field accurately retrieve geometrical information fulfill numerical conservativeness. interface well defined ...

Bubble migration in a vibrating zero gravity environment is numerically investigated using ANSYS-FLUENT software. A 3D CFD model developed describing the two-phase flow of nitrogen bubble immersed container full ethanol. The Volume Fluid (VOF) method and geometric reconstruction scheme are used to track gas–liquid interface. liquid vibrated horizontally x momentum with different frequencies fro...

Abstract This paper proposes a combined 1D-3D approach for the lubrication analysis of standard transmission including two helical gears. A lumped parameter model entire system is developed to predict flow distribution within circuit and localized pressure drops along lines. considers geometrical features real system, it combines experimental characteristic curves main hydraulic components. The...

The breakthrough in energy storage technology is the key issue for renewable penetration and compressed air (CAES) has demonstrated potential large-scale of power plants. Liquid piston (LP) been developed to achieve Isothermal CAES with improved efficiency, but description physical understanding coupled flow heat transfer dynamic behaviors are lacking. In this study, a 3D CFD model LP compresso...
