An efficient sharp-interface immersed boundary method for complex moving boundary flows based on adaptive Cartesian grids

Ning Fan, He Gao, Xianxu Yuan, Wenyang Duan et autres

Accurate moving-boundary treatment is a core challenge in flow simulations for maneuvering micro aircraft and high-speed trains. Adaptive Cartesian grids suit large-amplitude, high-frequency motions via automated meshing and dynamic refinement, but their boundary treatments suffer from limited accuracy, low robustness, or high …

Aerodynamic characteristics of a rotor near a wavy surface

Z X Sun, Shan Ma, Minghao Zhang, Wenyang Duan et autres

When helicopters hover near the water surface, the rotor thrust increases due to the water surface influence, which is similar to the ground effect and is known as the near water effect. While the rotor near calm water effect has been studied …

MAVEN-T: Reinforced Heterogeneous Distillation for Real-Time Multi-Agent Trajectory Prediction

Wenyang Duan, Zhenguo Gao, Jinguo Xian, Yi Shi

Trajectory prediction is a key component of autonomous driving systems because future motions directly affect collision checking, behavior planning, and control. The task remains challenging under dense interactions, heterogeneous behaviors, multimodal futures, and limited on-board computation. Existing graph, attention, and generative predictors …

Research on Ship Hull Hybrid Surface Mesh Generation Algorithm Based on Ship Surface Curvature Features

Wenyang Duan, Peixin Zhang, Kuo Yang, Limin Huang et autres

Mesh generation is a critical preprocessing step in Computational Fluid Dynamics. In ship hydrodynamics, existing mesh generation methods lack adaptability to complex hull surface geometries, necessitating repeated optimization. To address these issues, a new hybrid mesh generation strategy was proposed, integrating Non-Uniform …

A high-fidelity simulation method for moving bodies in flow fields based on dynamic Cartesian grids

Ning Fan, Li Jia, He Gao, Wenyang Duan et autres

With increasing demands for high-fidelity simulations of objects undergoing large-amplitude frequent motions in flow fields, traditional grid-based algorithms face challenges of insufficient computational efficiency and numerical instability. Although non-conformal Cartesian grids combined with immersed boundary methods (IBM) offer automation advantages, their results …
