Topic: Arctic Hydrogeology
I am currently focused on the complex transport processes that take place in the thawing Arctic permafrost due to global warming and how they affect the overall water cycle in the Arctic region. Not only is this important for the water cycle, the Arctic permafrost stores a huge amount of greenhouse gases like CH4, CO2, NOx which will get released as the Earth warms up and thus, will affect the global climate. I am interested in computational modeling and understanding the complex subsurface transport physics taking place in the dynamic Arctic subsurface.

Topic: Effect of changes in seawater head on seawater-groundwater Interaction. [Masters' Thesis]
I modeled the seawater interaction in groundwater in coastal aquifers with the help of CFD software like COMSOL and OpenFOAM. Most of the previous studies involving seawater-groundwater interference do not consider the matrix compression and rebound in time of diurnal tidal changes in the seawater level or seasonal changes due to rainfall and dry summers. I coupled the interaction considering the matrix response and saline concentration transport and dispersion of salinity along the interaction zone and tried to find out the effects in the mixing and groundwater contamination seasonally and diurnally.

Topic: Supercritical CO2 pushing brine in microfluidics: salt precipitation process
I programmed a code to simulate the mass-transfer and phase change across immiscible interfaces between supercritical CO2 using VOF in OpenFOAM in a T-Junction microfluidic channel to simulate CO2 injection during Carbon Capture and Sequestration. I also tested the different droplet regimes in temperature and pressure, which change much at higher pressure fluctuations. The simulations are done in 2D as well as 3D T-junctions to benchmark with the experimental data available. This gives us an idea about how the injected carbon dioxide gradually dissolves with the brine during CCS

Topic: Numerical study of Rayleigh Taylor instabilities in porous media with geoelectrics.[Report].
I programmed a coupled code in OpenFOAM to carry out the Rayleigh Taylor Instability in a porous media.I coupled that solver with another solver which calculates the effective conductivity of the media. The conductivity is computed by injecting current with a virtual pair of electrodes and measuring the potential difference between the two others. The computation is validated by comparing its outcome to known conductivities in several complex domains. The conductivity anisotropy is the ratio of the longitudinal to the transverse effective conductivities. -Effective conductivity calculation by simulating current injection through it as the instability evolves. These first results open up a range of opportunities to use electrical signals for the in-situ monitoring of CO2 sequestration in geological reservoirs.

Topic: Numerical simulations and Experimental study of CO2sequestration in deep aquifers. [Report].
I designed and performed a 3D-experiment for laser scanning of gravitational instability (Rayleigh Taylor instability) of miscible fluids in a porous media to study the vaiation of onset time and mixing length in pore scale of Rayleigh Taylor Instability. I also programmed a new solver in OpenFOAM to simulate the Rayleigh Taylor Instability with dispersion for two miscible fluids in porous media in both Darcy and pore scale.

Topic: Thermal transport in connected aquifers
Determined the mixing rate considering reactive transport of some specific elements responsible asradiogenic heat source in connected aquifers. Modeled the thermal transport of chemical species in porous media in COMSOL to estimate the average time required for mixing in porous media.

Those twelve years is the most awesome period of time in my student life. Learnt my basics, got interested in mathematics and physics which brought me to what I am pursuing today. Made some great friends with I am still in contact with. Learnt from some great teachers. Thanks to all of you, very very much!
