Particle detection in VOF-simulations with OpenFOAM
SoftwareX, 2020 The aim of this work is to improve the particle detection in the phase field of volume of fluid (VOF) simulations included in OpenFOAM. The reliable evaluation of the particle properties is a prerequisite for coupling the VOF method for the primary breakup with an Eulerian–Lagrangian simulation of the secondary breakup.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

Explicit‐Implicit Material Point Method for Dense Granular Flows With a Novel Regularized µ(I) Model
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The material point method (MPM) is widely employed to simulate granular flows. Although explicit time integration is favored in most current MPM implementations for its simplicity, it cannot rigorously incorporate the incompressible µ(I)‐rheology, an efficient model ubiquitously adopted in other particle‐based numerical methods. While operator‐

Numerical Study on Passing Flow Through Circular Channels with Side [PDF]
مهندسی منابع آب, 2017 Side weir is used as a slot in the side of main channel to direct excess flows that are above the weir crest. Such structures are used in control of flow level in irrigation, drainage networks and urban sewage disposal systems.

Improved droplet breakup models for spray applications [PDF]
, 2019 The current study examines the performance of two zero-dimensional (0D) aerodynamically-induced breakup models, utilized for the prediction of droplet deformation during the breakup process in the bag, multi-mode and sheet-thinning regimes.
