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...

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 ...

This article presents a three-dimensional CFD model and OpenCV code by comparing the flow over spillway with experimental data for use in studies. A 1/200-scale of real dam was created according to Froude similarity. In studies, velocity water depth were measured four different sections determined model. ANSYS Fluent simulations flows occurring during flood obtained. numerical model, two-phase ...

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...

Water impact phenomenon of general bow section is a critical event for planning hulls. In this paper, the water entry of several arbitrary bow sections is investigated. For this purpose, arbitrary bow shapes which are introduced by Lewis form approximation are considered. In order to obtain pressure distribution and free surface profile, volume of fluid (VOF) method coupled with finite volume m...

DPNTM is a versatile technology that leverages Scanning Probe Microscopy for applications in biotechnology, photomask repair, molecular-electronics, nano-electronics and mask-less lithography. The DPN process was augmented for biotechnology applications (genomics, proteomics) through the design, development, prototype fabrication, testing and manufacture of commercial microfluidic systems calle...

In Aluminium manufacturing the Soderberg pot is widely used. The study explains about the bubble motion in cryolite liquid in a Soderberg pot anode face using comprehensive VOF multiphase model in FLUENT, under the action of gravitation. The distribution of bubbles introduced under the anodes of an aluminum reduction cell at the initial time has fixed size. 2D simulation results are reported fo...

In order to design packed columns for multiphase operation it is necessary to include reliable data on the flow behavior in the model. Since experiments inside packings are very difficult to perform, CFD simulations are considered to be a sensible approach as numerical experiments. To obtain reliable results validation is inevitable. We present the validation of twoand three-phase film flow und...
