Thermodynamically Admissible Diffuse Interface Model for Nanoscale Transport of Dense Fluids
Rahul Bhattacharjee, Henning Struchtrup, Anirudh Singh Rana
We investigate interfacial fluid dynamics and heat transfer at nanoscales using an improved diffuse interface approach for liquid-vapor interfaces in non-equilibrium. Conventional…

A generalized fundamental solution technique for the regularized 13-moment system in rarefied gas flows
Himanshi, Lambert Theisen, Anirudh Singh Rana +2
In this work, we explore the method of fundamental solutions (MFS) for solving the regularized 13-moment (R13) equations for rarefied monatomic gases. While previous applications o…

Exploring external rarefied gas flows through the method of fundamental solutions
Himanshi, Anirudh Singh Rana, Vinay Kumar Gupta
The well-known Navier--Stokes--Fourier equations of fluid dynamics are, in general, not adequate for describing rarefied gas flows. Moreover, while the Stokes equations -- a simpli…
