Plug Flow and Cavitation in Rough Lubricated Contacts: Molecular Dynamics of Single- vs. Two-Component Fluids
Shubham Agarwal, Martin H. Müser
We present non-equilibrium molecular dynamics simulations of lubricated sliding between rough, deformable surfaces under conditions representative of mixed lubrication. One aim is…
Multi-Image Super Resolution Framework for Detection and Analysis of Plant Roots
Shubham Agarwal, Ofek Nourian, Michael Sidorov +4
Understanding plant root systems is critical for advancing research in soil-plant interactions, nutrient uptake, and overall plant health. However, accurate imaging of roots in sub…
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…
