They devised and tested a new formally stabilized formulation of the widely used k-omega turbulence model, making use of a modified eddy viscosity. In the present work, three new formally-stable k-omega turbulence model formulations are derived and tested in CFD simulations involving the flow and dynamics beneath large-scale plunging breaking waves.<br><br><b>Recorded Presentation from the vICCE (YouTube Link): <a href="https://youtu.be/T2fFRgq3I8E">https://youtu.be/T2fFRgq3I8E</a></b></html>}, number={36v}, journal={Coastal Engineering Proceedings}, author={Azorakos, Georgios and Larsen, Bjarke Eltard and Fuhrman, David R.}, year={2020}, month={Dec.}, pages={waves.19} }
