Application of the Standard Torbulance Model and the Volume of Fluid Method in Prediction of the Water Surface Profiles in a Hydraulic Jumps on the Triangular Corrugated Beds [PDF]

مهندسی منابع آب, 2016
The hydraulic jump is one of the most important topics In the field of open channel flow, which has been extensively investigated. When a flow condition changes from a supercritical to a subcritical regime, the result is an abrupt rise in the water ...

Numerical Prediction of Ship Resistance Based on Volume of Fluid Implicit Multi-Step Method

Journal of Marine Science and Engineering, 2023
The Volume of Fluid (VOF) method is used in two-phase fluid flow problems of ship hydrodynamic calculations, to capture the motion and distribution of the gas–liquid free surface. To ensure solution stability and accuracy, numerical simulations typically

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

Bottom‐Up Ice Growth Geometry Attenuates Shear Stress and Improves the Cryopreservation of Hematopoietic Stem/Progenitor Cells Under Low DMSO Concentrations

Biotechnology and Bioengineering, Volume 123, Issue 3, Page 582-597, March 2026.
ABSTRACT Studies on cell cryopreservation have been limited by the complexity of the freezing process and challenges on controlling ice formation, managing cooling rates, and optimizing cryoprotectant concentrations. The objective of this study is to evaluate the impact of bottom‐up and conventional radial freezing on the viability of mammalian cells ...

Analysis of Turbulent Modeling for Free‐Surface Flows Using a Hybrid RANS‐LES Model and Particle‐Based Moving Particle Semi‐Implicit Method

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.
A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Parametric Study on Wave Interaction with a Porous Submerged Rubble Mound Breakwater Using Modified N-S Equations and Cut-Cell Method

International Journal of Maritime Technology, 2016
In this paper wave transformation in a submerged sloped breakwater and its hydraulic performance was simulated by developing a numerical model in Fortran. The code was established by combining porous flow and a two-phase model using VOF method.
