Journal ArticleDOI
A Volume of Fluid Based Method for Fluid Flows with Phase Change
Samuel W. J. Welch,John Wilson +1 more
TL;DR: In this article, a numerical method for simulation of flows with mass transfer due to changes of phase is presented, where the authors use a volume of fluid (VOF) based interface tracking method in conjunction with a mass transfer model and a model for surface tension.
Journal ArticleDOI
Two-phase electrohydrodynamic simulations using a volume-of-fluid approach
Gaurav Tomar,D. Gerlach,Gautam Biswas,N. Alleborn,Ashutosh Sharma,F. Durst,Samuel W. J. Welch,Antonio Delgado +7 more
TL;DR: A weighted harmonic mean interpolation scheme is proposed to smoothen the electric properties in the diffused transition region (interface) of two-phase electrohydrodynamic flows under the volume-of-fluid paradigm.
Journal ArticleDOI
Application of Time-Based Fractional Calculus Methods to Viscoelastic Creep and Stress Relaxation of Materials
TL;DR: In this paper, the quasi-static viscoelastic response of polymeric materials is investigated utilizing constitutive models based on fractional calculus analysis techniques using time-based fractional analysis techniques.
Journal ArticleDOI
Direct simulation of vapor bubble growth
TL;DR: In this article, the authors present a numerical method directed towards the local simulation of axisymmetric vapor bubble growth using an interface tracking method in conjunction with a finite volume method on a moving unstructured mesh.
Journal ArticleDOI
Local simulation of two-phase flows including interface tracking with mass transfer
TL;DR: In this article, a moving mesh, two-dimensional finite volume method suitable for tracking interfaces across which there is mass transfer is presented, where the interface is tracked by nodes representing the liquid and vapor sides at the same spatial location.
