Topic: Hydrological ModellingGuide: Prof. Aditya BandopadhyayTransverse Macrodispersion in Groundwater Flows• Numerically showcased the critical flaw in current particle transport models used in commercial groundwater modelling softwares.• Modelled particle transport in 2D and 3D Darcy scale correlated porous media with pollock particle tracking implemented in MATLAB.• Showcased how errors associated with numerical particle tracking methods can generate spurious transverse macrodispersion in steady 3D flow which can lead to wrong interpretations.• Work was published in Water Resources Research( http://doi.org/10.1029/2022WR033059 )Transport in Self Affine Fractured Media• Generated self affine fractured media using MATLAB to study transport characteristics of passive tracers.• Modelled transport using Basilisk(C library) and used CloudCompare for point cloud pre processing and visualization.Transport in 2D correlated porous media using FEM• Developed codebase to model transport in 2D correlated darcy scale porous media using FEM.• Implemented the model in FEniCS and compared the results with FVM and found them to be in good agreement.Teaching Assistant for NPTEL course titled Tools in Scientific Computing• Prepared and graded assignments.• Moderated the doubt session group and helped the learners in their queries.• Documented the codebase in Octave GNU and Python.

Project: Transport in Porous MediaGuide: Prof. Aditya Bandopadhyay• Modelled Eulerian simulations in C(Basilisk) to study transport of passive tracers in 2D correlated porous media.• Implemented adaptive grids to achieve reduced computation time while maintaining same level of accuracy as fixed grid methods. • Quantified mixing measures like scalar spreading length, dilution Index and elongation rates with post processing in MATLAB.• Compared results with existing statistical particle tracking methods and found them to be in good agreement showcasing the viability of Eulerian methods for transport simulations.
