# My Sandbox
Welcome to the README of my sandbox.
Here I provide an overview of the projects under [/sandbox/vatsal/](). I mainly work with surface tension driven flows.

## Repositories

### [Drop impact forces]
Coming soon. This repository contains the code for the paper [Impact Forces of Water Drops Falling on Superhydrophobic Surfaces](https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.129.104501).

#### [Bursting Bubble](BurstingBubble/)
We investigate the classical problem of bubble bursting at a liquid-gas interface, but now in the presence of a viscoplastic liquid medium. [arXiv](https://arxiv.org/abs/2101.07744)<br\>

P.S. Embedding videos from youtube works for Safari browser as well. 

#### [Drop on drop impact](DropOnDropImpact/)
We investigate the dynamics of an oil drop impacting an identical sessile drop sitting on a superamphiphobic surface.<br\>

* [dropOnDropImpact.c](/sandbox/vatsal/DropOnDropImpact/dropOnDropImpact.c)
* [DropDeposition.c](sandbox/vatsal/DropOnDropImpact/DropDeposition.c): For [dropOnDropImpact.c](/sandbox/vatsal/DropOnDropImpact/dropOnDropImpact.c), assuming the sessile drop to be spherical is inaccurate. In this code, we get the shape of the sessile drop.

#### [Generalized Newtonian Fluids](GenaralizedNewtonian/)
* [Couette Flow](/sandbox/vatsal/GenaralizedNewtonian/Couette_NonNewtonian.c)
* [Lid Driven Cavity flow (Bingham Fluid)](/sandbox/vatsal/GenaralizedNewtonian/LidDrivenBingham.c)
* [Surface capillary waves (Bingham Fluid)](/sandbox/vatsal/GenaralizedNewtonian/SurfaceWavesBingham.c)

#### [Three-phase Contact Line](ThreePhase/)
This folder contains the simulation for the implementation of three-phase contact line in Basilisk C. The codes present here originated from the discussions [here](https://groups.google.com/forum/#!topic/basilisk-fr/Sj_qNMXOfXE).<br/>

* [Encapsulation Case](/sandbox/vatsal/ThreePhase/Encapsulation.c)
* [Three-phase properties calculations](/sandbox/vatsal/ThreePhase/three-phase.h)
* [Three-phase surface tension term](/sandbox/vatsal/ThreePhase/tension_three-phase.h)
* [Poster](https://www.dropbox.com/s/p9dyqo4yoe1dedj/Vatsal_PosterEncapsulationv4.pdf?dl=0)
