Wellposedness of the discontinuous ODE associated with two-phase flows
Dieter Bothe
We consider the initial value problem \[ \dot x (t) = v(t,x(t)) \;\mbox{ for } t\in (a,b), \;\; x(t_0)=x_0 \] which determines the pathlines of a two-phase flow, i.e.\ i…
Boundedness-Preserving Implicit Correction of Mesh-Induced Errors for VoF Based Heat and Mass Transfer
Simon Hill, Daniel Deising, Thomas Acher +3
Spatial discretisation of geometrically complex computational domains often entails unstructured meshes of general topology for Computational Fluid Dynamics (CFD). Mesh skewness is…
On the Interface Formation Model for Dynamic Triple Lines
Dieter Bothe, Jan Prüss
This paper revisits the theory of Y. Shikhmurzaev on forming interfaces as a continuum thermodynamical model for dynamic triple lines. We start with the derivation of the balances…
On Two-Phase Flows with Soluble Surfactant
Dieter Bothe, Matthias Köhne, Jan Prüss
The presence of surfactants has a pronounced effect on the surface tension and, hence, on the stress balance at the phase separating interface of two-phase flows. The transport of…
Experiments and Direct Numerical Simulations of binary collisions of miscible liquid droplets with different viscosities
C. Focke, D. Bothe, M. Kuschel +1
Binary droplet collisions are of importance in a variety of practical applications comprising dispersed two-phase flows. The background of our research is the prediction of propert…
