A particle finite element-based model for droplet spreading analysis
Mahrous, Elaf; Jarauta, Alex; Chan, Thomas; Ryzhakov, Pavel; Weber, Adam Z.; Roy, R. Valéry; Secanell, Marc (2020-04)
Article
Accés obertA particle finite element method-based model is proposed to analyze droplet dynamics problems, particularly droplet spreading on solid substrates (wetting). The model uses an updated Lagrangian framework to formulate the ... -
Challenges in computational modeling of two-phase transport in polymer electrolyte fuel cells flow channels: a review
Ryzhakov, Pavel; Jarauta, Alex (2018-11)
Article
Accés obertExcess of liquid water in gas channels of polymer electrolyte fuel cells is responsible for malfunctioning of these devices. Not only it decreases their efficiency via partial blockage of reactants and pressure drop, but ... -
Numerical study of roughness and contact angle effects on water transport in a gas channel
Jarauta, Alex; Chan, Thomas; Weber, Adam Z.; Ryzhakov, Pavel; Pons Prats, Jordi; Secanell, Marc (2017)
Text en actes de congrés
Accés obertWater accumulation in fuel cell anode and cathode channels can lead to hydrogen starvation and therefore, severe electrode degradation, and significantly fuel cell performance deterioration. For this reason, liquid water ...
