A Scalable Sharp-Interface Immersed Boundary Method for Moving Boundary Flow Simulation on Multi-GPU Systems
Sushrut Kumar, Joshua Romero, Massimiliano Fatica +2
Sharp-interface immersed boundary methods provide a versatile framework for simulating flows with complex moving boundaries, but their irregular data structures, dynamic sparsity,…
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…
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…
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,…
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…
Contribution of spanwise and cross-span vortices to the lift generation of low-aspect-ratio wings: Insights from force partitioning
Karthik Menon, Sushrut Kumar, Rajat Mittal
This study reports on the vortex-induced lift production mechanisms in low Reynolds number flows over low aspect-ratio rectangular wings. We use a rigorous force partitioning metho…
