Co-moving volumes and the Reynolds transport theorem for two-phase flows
Dieter Bothe, Matthias Köhne
We consider the local kinematics at fluid interfaces in sharp-interface two-phase flows with phase change and interfacial slip. In this setting the governing velocity field is disc…
A two-sided subgrid-scale model for mass transfer across fluid interfaces
Moritz Schwarzmeier, Tomislav Marić, Željko Tuković +1
The occurrence of extremely thin concentration boundary layers at fluid interfaces for high local Péclet numbers is a severe obstacle for efficient and accurate numerical simulatio…
A continuum thermodynamic model of the influence of non-ionic surfactant on mass transfer from gas bubbles
Dieter Bothe, Akio Tomiyama
Mass transfer of gaseous components from rising bubbles to the ambient liquid depends not only on the chemical potential difference of the transfer component but also on the interf…
Multi-Velocity Sharp-Interface Continuum Thermodynamics of Fluid Systems with Adsorption
Dieter Bothe
We revisit the sharp-interface continuum thermodynamics of two-phase multicomponent fluid systems, accounting for partial mass and partial momentum balances both in the bulk phases…
Mathematical analysis of the velocity extension level set method
Dieter Bothe, Kohei Soga
A passively advected sharp interface can be represented as the zero level set of a level set function . The linear transport equation is the sim…
A Two-Field Formulation for Surfactant Transport within the Algebraic Volume of Fluid Method
T. Antritter, T. Josyula, T. Marić +5
Surfactant transport plays an important role in many technical processes and industrial applications such as chemical reactors, microfluidics, printing and coating technology. High…
