Renormalization Group theory outperforms other approaches in statistical comparison between upscaling techniques for porous media
Shravan Hanasoge, Umang Agarwal, Kunj Tandon +1
Determining the pressure differential required to achieve a desired flow rate in a porous medium requires solving Darcy's law, a Laplace-like equation, with a spatially varying ten…
Iterative inversion of synthetic travel times successful at recovering sub-surface profiles of supergranular flows
Jishnu Bhattacharya, Shravan M. Hanasoge, Aaron C. Birch +1
We develop a helioseismic inversion algorithm that can be used to recover sub-surface vertical profiles of 2-dimensional supergranular flows from surface measurements of synthetic…
Sensitivity of Helioseismic Measurements of Normal-mode Coupling to Flows and Sound-speed Perturbations
Shravan M. Hanasoge, Martin Woodard, H. M. Antia +2
In this article, we derive and compute the sensitivity of measurements of coupling between normal modes of oscillation in the Sun to underlying flows. The theory is based on first-…
Finite-frequency sensitivity kernels in spherical geometry for time-distance helioseismology
Krishnendu Mandal, Jishnu Bhattacharya, Samrat Halder +1
The inference of internal properties of the Sun from surface measurements of wave travel times is the goal of time-distance helioseismology. A critical step toward the accurate int…
Seismic sensitivity of Normal-mode Coupling to Lorentz stresses in the Sun
Shravan M. Hanasoge
Understanding the governing mechanism of solar magnetism remains an outstanding challenge in astrophysics. Seismology is the most compelling technique with which to infer the inter…
Numerical analysis of the lattice Boltzmann method for simulation of linear acoustic waves
Dattaraj B. Dhuri, Shravan M. Hanasoge, Prasad Perlekar +1
We analyse a linear lattice Boltzmann (LB) formulation for simulation of linear acoustic wave propagation in heterogeneous media. We employ the single-relaxation-time Bhatnagar-Gro…
