Manoeuvring simulations using the overset grid technology in foam-extend
2018Full scale turning circle manoeuvre is simulated using the Finite Volume (FV) based CFD software called the Naval Hydro Pack, which is based on foam-extend. Results are directly compared to sea trial measurements for two propeller rotation rates. Two different approaches for modelling the free surface are investigated: as single–phase flow model with a

Wave Diffraction CFD Nonlinear Time–Spectral Simulations in foam–extend
2016Harmonic Balance (HB) method is applied to the problems of surface gravity waves in the Naval Hydro pack in foam–extend, which enables time–spectral simulations of wave diffraction. HB transforms a transient problem into a set of coupled steady state equations by assuming a temporally periodic flow.

pUCoupledFoam - an open source coupled incompressible pressure-velocity solver based on foam-extend
2014Due to the general slow convergence of steady-state incompressible solvers, coupled ap- proaches are attractive alternatives. Such implicit solvers are well suited within the ex- isting generic block matrix format available with foam-extend. In this work, new implicit discretisation operators as well as assembling tools and matrix solvers are described

Enhanced Turbomachinery Capabilities for foam-extend: Development and Validation
2016Turbomachinery simulations represent one of the most challenging fields in Computational Fluid Dynamics (CFD). In the recent years, the general CFD ca- pabilities of foam-extend have been extended by introducing and maintaining addi- tional features specifically needed for turbomachinery applications, with the aim of offering a high quality CFD tool ...
