Plug Flow and Cavitation in Rough Lubricated Contacts: Molecular Dynamics of Single- vs. Two-Component Fluids
Shubham Agarwal, Martin H. Müser
The paper uses non‑equilibrium molecular dynamics to study how single‑component (water, n‑dodecane) and immiscible two‑fluid lubricants behave in rough, deformable contacts, reveal…
On the flash temperature in sliding contacts
M. H. Müser, B. N. J. Persson
The temperature increase in the contact regions between solids in sliding contact can easily reach several hundred Kelvin and thereby dramatically affect friction and wear. The cla…
Computing finite--temperature elastic constants with noise cancellation
Debashish Mukherji, Marcus Müller, Martin H. Müser
Elastic constants are central material properties, frequently reported in experimental and theoretical studies. While their computation is straightforward in the absence of thermal…
Granite sliding on granite: friction, wear rates, surface topography, and the scale-dependence of rate-state effects
Sergey V. Sukhomlinov, Martin H. Müser, B. N. J. Persson
We study tribological granite-granite contacts as a model for tectonic faulting, combining experiments, theory, and molecular dynamics simulations. The high friction in this system…
Finite-temperature properties of the Frenkel-Kontorova model: Relation to tribological systems and fluid rheology
Shubham Agarwal, Martin H. Müser
The Frenkel-Kontorova model is a simple yet generic framework for the description of tribological phenomena and processes, including dry solid friction and the motion of adsorbed l…
Advanced Langevin thermostats: Properties, extensions to rheology, and a lean momentum-conserving approach
Shubham Agarwal, Sergey V. Sukhomlinov, Marc Honecker +1
The Langevin equation accounts for unresolved bath degrees of freedom driving the system toward the bath temperature. Because of this, numerical solutions of the Langevin equation…
