Abstract Simulating complex hydraulic conditions, particularly two-phase flows over spillway chutes, can be achieved with high accuracy using three-dimensional numerical models. This study investigates the potential for vacuum generation and cavitation phenomena on the Aghchai Dam service spillway through numerical simulations conducted

VOF Calculations of Countercurrent Gas-Liquid Flow in a PWR Hot Leg
Science and Technology of Nuclear Installations, 2012 We improved the computational grid and schemes in the VOF (volume of fluid) method with the standard 𝑘−𝜀 turbulent model in our previous study to evaluate CCFL (countercurrent flow limitation) characteristics in a full-scale PWR hot leg (750 mm diameter),

An improved mathematical model to simulate mold filling process in high pressure die casting using CLSVOF method and CSF model [PDF]
China Foundry, 2015 A 3D mathematical model was proposed to simulate the mold filling process in high-pressure die casting (HPDC) to improve accuracy considering the surface tension. Piecewise liner interface calculation (PLIC) and volume of fluid (VOF) methods were used to
