PhyNiKCE: A Neurosymbolic Agentic Framework for Autonomous Computational Fluid Dynamics
E Fan, Lisong Shi, Zhengtong Li +1
The deployment of autonomous agents for Computational Fluid Dynamics (CFD), is critically limited by the probabilistic nature of Large Language Models (LLMs), which struggle to enf…
Fusion of Simulation and Experiment Data for Hypersonic Flow Field Prediction via Pre-Training and Fine-Tuning
Yuan Jia, Guoqin Zhao, Hao Ma +3
Accurate prediction of hypersonic flow fields over a compression ramp is critical for aerodynamic design but remains challenging due to the scarcity of experimental measurements su…
UAV-CodeAgents: Scalable UAV Mission Planning via Multi-Agent ReAct and Vision-Language Reasoning
Oleg Sautenkov, Yasheerah Yaqoot, Muhammad Ahsan Mustafa +5
We present UAV-CodeAgents, a scalable multi-agent framework for autonomous UAV mission generation, built on large language and vision-language models (LLMs/VLMs). The system levera…
Analysis and applications of the upwind conservation element and solution element scheme for compressible flow simulations
Yazhong Jiang, Lisong Shi, Chih-Yung Wen
The upwind conservation element and solution element (CESE) scheme is an alternative discontinuity-capturing numerical approach to solving hyperbolic conservation laws. To evaluate…
Detonation propagation in three-dimensional continuous curved ducts
Lisong Shi, Chih-Yung Wen, Xuxu Sun +1
In this paper, 3D detonation numerical studies are conducted using reactive Euler equations in both straight and curved channels. These simulations are compared to investigate the…
