Two-fluid dynamics is a challenging subject, rich both in physics and in practical applications, which range from manufacturing to lubricated transport. Mechanisms unique to a flow can be exploited to enhance functionality in applications. For example, density-matching can be used to depress the effect of gravity, or of centripetal acceleration in rotating systems, making it possible to manipul...

Stirred tanks are widely used in process industries for blending of singleand/or multiple-phase fluids, which often involves mass and/or heat transfer, chemical reactions, etc. Deep knowledge of flow field in the stirred tank is necessary to carry out these unit operations efficiently. As a result, extensive investigations of the flow in stirred tanks have been conducted over the past several d...

Spur dike is a common hydraulic structure, which is widely used in hydraulic engineering such as channel regulation, flood prevention and river diversion for preserving the desired water depth, deflecting the main current and protecting river banks. In actual operations, spur dikes exert influence on river system usually in the form of groups, and the flow field around spur dike group is compli...

Volume of fluid (VOF) methods are extensively used to track interfaces in numerical simulations, and many VOF algorithms require that the interface be reconstructed geometrically. For this purpose, Piecewise Linear Interface Construction (PLIC) technique is most frequently used, which for reasons geometric complexity can slow difficult implement. Here, we propose an alternative neural network b...

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 ...

The transport of fluid, heat ,and particles (bubbles and solid inclusions) in flowing molten steel is investigated in steel refining ladles, the continuous casting tundish, continuous casting mold and strand, and steel ingot casting processes. The two-equation k-ε model is used to simulate the turbulence. Multiphase fluid flow is numerically simulated with a Lagrangian-Eulerian approach, an Eul...
