Physics of FluidsZinner, Carl Philipp; Öttinger, Hans Christian (2019)One of the major challenges in extending hydrodynamics to far from equilibrium gas flows comes with the need of new boundary conditions for any new modeling approach. The difficulty lies in finding an accurate set of physical conditions at the boundary which simultaneously form a well-posed system of equations. In this paper, we study a system of moment equations for rarefied gas flows that comes equipped with an entropy. This allows a straightforward derivation of boundary conditions which are consistent with the mathematical requirements of the system. The complete nonlinear system is simulated in a rarefied channel flow setting and compared to standard approaches. The results exhibit most of the desired rarefaction effects, such as temperature jump and velocity slip at the wall. - Generalized Doi-Ohta Model for Multiphase Flow Developed via GENERICItem type: Journal Article
AIChE JournalWagner, Norman J.; Öttinger, Hans Christian; Edwards, Brian J. (1999) - Composite higher derivative theory of gravityItem type: Journal Article
Physical Review ResearchÖttinger, Hans Christian (2020)We investigate a higher derivative theory that belongs to the class of composite field theories. Starting from the Yang-Mills theory based on the Lorentz group, we express the gauge vector fields in terms of the tetrad decomposition of a space-time metric with a nontrivial coupling constant. The resulting composite gauge theory is a natural candidate for an alternative theory of pure gravity. In the limit of vanishing coupling constant, all classical high-precision tests for theories of gravity are passed. An exact static isotropic solution is found, which is less singular than the Schwarzschild solution of general relativity. Composite field theories come with a natural canonical Hamiltonian formulation and a natural set of constraints, so that they provide an ideal setting for future quantization. Finally, we propose possible couplings of the gravitational field to matter. - Bridging length and time scales in sheared demixing systemsItem type: Journal Article
