Development of a CFD Solver for Primary Diesel Jet Atomization in FOAM-Extend [PDF]

open access: yesSAE Technical Paper Series, 2019
<div class="section abstract"><div class="htmlview paragraph">Ongoing development of a CFD framework for the simulation of primary atomization of a high pressure diesel jet is presented in this work. The numerical model is based on a second order accurate, polyhedral Finite Volume (FV) method implemented in <span class="monospace"> ...

Rigid Polyurethane Foams Extended with Partially Delactosed Whey Powder

open access: yesJournal of Dairy Science, 1972
Abstract Partially dalactosed whey powder was incorporated as an extender in rigid polyurethane foam formulations. Amounts of delactosed whey powder from 0 to 60.0% partially replaced six types of polyether polyols (OH No. 410 to 768). Polymethylene polyphenylisocyanate was the polyisocyanate and water was the blowing agent. Physical properties of the

An Experimental and Numerical Investigation on Bubble Growth in Polymeric Foams

open access: yesEntropy, 2022
The cellular morphology of thermoplastic polymeric foams is a key factor for their performances. Three possible foam morphologies exist, namely, with closed cells, interconnected cellular structure, and open cells.

Facile Route to Achieve a Hierarchical CuO/Nickel-Cobalt-Sulfide Electrode for Energy Storage

open access: yesMicromachines, 2023
Herein, a novel self-supporting CuO/nickel-cobalt-sulfide (NCS) electrode was designed in a two-step electrodeposition technique followed by a calcination process.

Immediate effects of self-myofascial release on latent trigger point sensitivity: a randomized, placebo-controlled trial

open access: yesBiology of Sport, 2018
Latent myofascial trigger points (MTrP) have been linked to several impairments of muscle function. The present study was conducted in order to examine whether a single bout of self-myofascial release using a foam roller is effective in reducing MTrP ...

Efficient solution of 3D electromagnetic eddy-current problems within the finite volume framework of OpenFOAM

open access: yes, 2017
Eddy-current problems occur in a wide range of industrial and metallurgical applications where conducting material is processed inductively. Motivated by realising coupled multi-physics simulations, we present a new method for the solution of such ...

Numerical analysis of an initial design of a counter-rotating pump-turbine [PDF]

open access: yes, 2021
Renewable sources of energy are on the rise and will continue to increase the coming decades. A common problem with the renewable energy sources is that they rely on effects which cannot be controlled, for instance the strength of the wind or the ...

Fluid-structure interaction simulations with a LES filtering approach in solids4Foam [PDF]

open access: yes, 2021
The goal of this paper is to test solids4Foam, the fluid-structure interaction (FSI) toolbox developed for foam-extend (a branch of OpenFOAM), and assess its flexibility in handling more complex flows.

Effects of larval foam-making and prolonged terrestriality on morphology, nitrogen excretion and development to metamorphosis in a Leptodactylid frog [PDF]

open access: yesPeerJ
At ontogenetic transitions, animals often exhibit plastic variation in development, behavior and physiology in response to environmental conditions. Most terrestrial-breeding frogs have aquatic larval periods.
