An exponential time-differencing method for monotonic relaxation systems
Aursand, Peder; Evje, Steinar; Flåtten, Tore; Teigen, Knut Erik; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2014)We present first and second-order accurate exponential time differencing methods for a special class of stiff ODEs, denoted as monotonic relaxation ODEs. Some desirable accuracy and robustness properties of our methods are ... -
Development and use of interface-capturing methods for investigation of surfactant-covered drops in electric fields
Teigen, Knut Erik (Doktoravhandlinger ved NTNU, 1503-8181; 2010:163, Doctoral thesis, 2010)This thesis investigates the development and use of interface-capturing methods for detailed simulations of surfactant-covered drops in electric fields. A mathematical model is established for the full hydrodynamic ... -
Sharp interface simulations of surfactant-covered drops in electric fields
Teigen, Knut Erik; Lervåg, Karl Yngve; Munkejord, Svend Tollak (Chapter, 2010)A level-set method for computations of interfacial flows with insoluble surfactants with electric fields is presented. The discontinuities at the interface are captured in a sharp manner using the ghost-fluid method. The ...
