Numerical and Experimental Investigation of Static Wetting Morphologies of Aqueous Drops on Lubricated Slippery Surfaces Using a Quasi-Static Approach
Shivam Gupta, Bidisha Bhatt, Meenaxi Sharma +1
Due to the slow dynamics of the wetting ridge, it is challenging to predict the wetting morphology of liquid drops on thin lubricant coated surfaces. It is hypothesized that when a…
Reversible Dewetting of Thin Lubricating Films Underneath Aqueous Drops Using External Electric Field
Bidisha Bhatt, Shivam Gupta, Vasudevan Sumathi +2
The stability of thin liquid films on a surface depends on the excess free energy of the system involving various short-range and long-range interactions. In an unstable condition,…
Dewetting of Thin Lubricating Films Underneath Aqueous Drops on Slippery Surfaces
Bidisha Bhatt, Shivam Gupta, Meenaxi Sharma +1
Stability of thin lubricating fluid coated slippery surfaces depends on the surface energy of the underlying solid surface. High energy solid surfaces, coated with thin lubricating…
Anisotropic Stick-Slip Behavior of Aqueous Drops on Lubricated Chemically Heterogeneous Slippery Surfaces
Meenaxi Sharma, Shivam Gupta, Bidisha Bhatt +3
Conventional slippery surfaces show isotropic drop mobility in all directions, but many applications require directional drop motion along a particular path only. In previous studi…
