TheoPhysEval: Assessing AI agents at autonomous theoretical physics problem solving
A. Ramesh Chandra, Aaghaz Mahajan, Ainesh Sanyal +32
We present a suite of 50 unpublished research-level theoretical physics problems with verifiable answers. Without AI assistance, a typical problem in our collection could be solved…
Preliminary experimental investigation on the interaction of a subaqueous dune like granular structure with a turbulent open channel flow
Durbar Roy, Ikbal Ahmed, Abdul Hakkim +1
We study the interaction of a subaqueous dune like granular structure with a turbulent open channel flow experimentally using optical diagnostics in the Shields and Froude paramete…
Insights into Transient Dynamics of Bacteria Laden Liquid Bridges
Kush Kumar Dewangan, Srinivas Rao S, Durbar Roy +3
We study evaporation and precipitate formation mechanics of bacteria-laden liquid bridge using experimental and theoretical analysis. Aqueous suspension of motile and non-motile Sa…
Evaporation of bacteria-laden surrogate respiratory fluid droplets: On a hydrophilic substrate versus contact-free environment confers differential bacterial infectivity
Amey Nitin Agharkar, Dipasree Hajra, Durbar Roy +4
The transmission of viruses/ bacteria cause infection predominantly via aerosols. The transmission mechanism of respiratory diseases is complex, including direct or indirect contac…
Insights into the mechanics of pure and bacteria-laden sessile whole blood droplet evaporation
Durbar Roy, Sophia M, Kush K Dewangan +5
We study the mechanics of evaporation and precipitate formation in pure and bacteria-laden sessile whole blood droplets in the context of disease diagnostics. Using experimental an…
Insights into bubble droplet interactions in evaporating polymeric droplets
Gannena K S Raghuram, Durbar Roy, D Chaitanya Kumar Rao +2
Polymer droplets subjected to a heated environment have significance in several fields ranging from spray drying and powder formation to surface coating. In the present work, we in…
Future Research Perspective on the Interfacial Physics of Non-Invasive Glaucoma Testing in Pathogen Transmission from the Eyes
Durbar Roy, Saptarshi Basu
Non-contact Tonometry (NCT) is a non-invasive ophthalmologic technique to measure intraocular pressure (IOP) using an air puff for routine glaucoma testing. Although IOP measuremen…
Insights into air cushion dynamics during drop impact on heated substrate at low impact energy
Durbar Roy, Srinivas Rao S, Vishnu Hariharan +1
We study the air layer dynamics beneath a drop impinging a heated surface at low impact energy using high-speed reflection interferometry imaging and theoretical analysis. The air…
On the mechanics of droplet surface crater during impact on immiscible viscous liquid pool
Durbar Roy, Sophia M, Saptarshi Basu
We study drop impacts on immiscible viscous liquid pool and investigate the formation of droplet surface craters using experimental and theoretical analysis. We attribute the forma…
Droplet impact on immiscible liquid pool: Multi-scale dynamics of entrapped air cushion at short timescales
Durbar Roy, Sophia M, Srinivas Rao S +1
We have detected unique hydrodynamic topology in thin air film surrounding the central air dimple formed during drop impact on an immiscible liquid pool. The pattern resembles spin…
On the Thermofluidics of a Steady Laminar Jet Impacting on a Rotating Hot Plate: An ab-initio Scaling Perspective
Durbar Roy, Saptarshi Basu
We provide an ab-initio scaling analysis for liquid film thickness and Nusselt number of a steady laminar jet impacting a rotating heated plate. The limiting scaling regimes incorp…
Dynamics of Droplet Generation from Corneal Tear Film during Non-contact Eye Procedure in the Context of COVID-19
Durbar Roy, Sophia M, Abdur Rasheed +4
Non-invasive medical diagnostics demonstrate a propensity for droplet generation and should be studied to devise risk mitigation strategies against the spread of the SARS-CoV-2 vir…
