A Scalable OpenLB LAMMPS Framework for Fully Resolved Simulations of Hindered Settling of Arbitrary Non-Spherical Particles
Varghese Babu, Adrian Kummerländer, Mathias J. Krause +2
Hindered settling of non spherical particles remains significantly less understood than spherical particles due to the computational challenges in resolving the complex contact mec…
Magnetohydrodynamic equilibrium and neutronics study on MAST-U using Jenga framework
Saptarshi Rajan Sarkar, Rahul Babu Koneru, Ravi Gupta +4
Tokamak design is inherently challenging due to several cross-competing effects which require a careful and calibrated treatment to obtain an optimal operational envelope. Incorpor…
Design and mechanical analysis of the PRAGYA tokamak vacuum vessel
Ravi Gupta, Rahul Babu Koneru, Saptarshi Rajan Sarkar +4
PRAGYA is India's first privately developed low aspect ratio tokamak designed by Pranos Fusion Energy. The device is designed for a plasma major radius (R0) of about 0.4 m, a plasm…
Kinetic-based regularization: Learning spatial derivatives and PDE applications
Abhisek Ganguly, Santosh Ansumali, Sauro Succi
Accurate estimation of spatial derivatives from discrete and noisy data is central to scientific machine learning and numerical solutions of PDEs. We extend kinetic-based regulariz…
Deep Neural Networks as Discrete Dynamical Systems: Implications for Physics-Informed Learning
Abhisek Ganguly, Santosh Ansumali, Sauro Succi
We revisit the analogy between feed-forward deep neural networks (DNNs) and discrete dynamical systems derived from neural integral equations and their corresponding partial differ…
Fluid-kinetic multiscale solver for wall-bounded turbulence
Akshay Chandran, Praveen Kumar Kolluru, Berni J. Alder +2
We present a two-level (fluid-kinetic) coupling procedure for the simulation of wall-bounded flows at Reynolds numbers up to thousands. The method combines a kinetic Direct Simulat…
