GPU-Accelerated Simulations of Moving Boundary Problems and Fluid-Structure Interaction at Extreme Scales
Sushrut Kumar, Joshua Romero, Jung-Hee Seo +2
Computational fluid dynamics and fluid-structure interaction simulations involving moving and deforming bodies is extremely hard. In this work, we present a graphical processing un…
AeTHERON: Autoregressive Topology-aware Heterogeneous Graph Operator Network for Fluid-Structure Interaction
Sushrut Kumar
Surrogate modeling of body-driven fluid flows where immersed moving boundaries couple structural dynamics to chaotic, unsteady fluid phenomena remains a fundamental challenge for b…
Flow-induced dorso-ventral deformation enhances propulsive efficiency in flexible caudal fins
Sushrut Kumar, Matthew J. McHenry, Jung-Hee Seo +1
Fish swim with flexible fins that stand in stark contrast to the rigid propulsors of engineered vehicles. Using numerical simulations of the dynamics of flow-structure interaction,…
A GPU-Accelerated Sharp Interface Immersed Boundary Solver for Large Scale Flow Simulations
Sushrut Kumar, Joshua Romero, Jung-Hee Seo +2
Immersed boundary methods (IBMs) facilitate the simulation of flows around stationary, moving, and deforming bodies on Cartesian grids. However, extending these simulations to the…
Computational Modeling and Analysis of the Coupled Aero Structural Dynamics in Bat Inspired Wings
Sushrut Kumar, Jung-Hee Seo, Rajat Mittal
We employ a novel computational modeling framework to perform high-fidelity direct numerical simulations of aero-structural interactions in bat-inspired membrane wings. The wing of…
