Rheology of hydrating cement paste: crossover between two aging processes
Atul Varshney, Smita Gohil, B. A. Chalke +4
The roles of applied strain and temperature on the hydration dynamics of cement paste are uncovered in the present study. We find that the system hardens over time through two diff…
Oscillatory elastic instabilities in an extensional viscoelastic flow
Atul Varshney, Eldad Afik, Yoav Kaplan +1
Dilute polymer solutions are known to exhibit purely elastic instabilities even when the fluid inertia is negligible. Here we report the quantitative evidence of two consecutive os…
Electric-field-induced turbulent energy cascade in an oil-in-oil emulsion
Atul Varshney, Mayur Sathe, Shankar Ghosh +3
We observe electro-hydrodynamically driven turbulent flows at low Reynolds numbers in a two-fluid emulsion consisting of micron-scale droplets. In the presence of electric fields,…
