Isogeometric divergence-conforming variational multiscale formulation of incompressible turbulent flows
van Opstal, Timo Matteo; Yan, Jinhui; Coley, Christopher; Evans, John Andrew; Kvamsdal, Trond; Bazilevs, Yuri (Journal article, 2016)A new residual-based variational multiscale (RBVMS) formulation for incompressible turbulent flows is proposed that is suitable for discretization using divergence-conforming B-splines. The proposed methodology results in ... -
Isogeometric methods for CFD and FSI-simulation of flow around turbine blades
van Opstal, Timo Matteo; Fonn, Eivind; Holdahl, Runar; Kvamsdal, Trond; Kvarving, Arne Morten; Mathisen, Kjell Magne; Nordanger, Knut; Okstad, Knut Morten; Rasheed, Adil; Tabib, Mandar (Journal article; Peer reviewed, 2015)Coupled fluid-structure interaction simulations of wind turbines have traditionally been considered computationally too expensive to carry out. However, more powerful computers and better solution techniques based on ... -
Isogeometrisk analyse av Boussinesq ligningene
Abdulhaque, Abdullah (Master thesis, 2016)In this master thesis, I have solved the Boussinesq equations with Isogeometric Analysis to study heat transfer coupled with air circulation. The Boussinesq equations consist of the Navier-Stokes equations and the ...
