Vertical-axis wind turbines (VAWT) are excellent candidates to complement traditional wind
turbines and increase the total wind energy capacity. Development of VAWT has been …

The finite-time Lyapunov exponent (FTLE) method is a mature and practical method for
analyzing the characteristics of Lagrangian coherent structures. It can be used for studying …

The transient pressure field around a moderately thick airfoil is studied as it undergoes ramp-
type pitching motions at high Reynolds numbers and low Mach numbers. A unique set of …

Airfoil stall plays a central role in the design of safe and efficient lifting surfaces. We typically
distinguish between static and dynamic stall based on the unsteady rate of change of an …

The lift generation mechanism of leading-edge vortex (LEV) in the case of a pitching and
plunging plate is studied using an experimental approach and the improved discrete vortex …

In this paper, we present an approach to obtain a desired leading-edge vortex (LEV)
shedding pattern from unsteady airfoils through the execution of suitable motion kinematics …

水翼非定常流动结构与水动力特性的数值模拟, 并基于有限域涡量矩理论定量表征了局部旋涡 …

The objective of this study is to investigate the hydrodynamic forces acting on a pitching
Clark-Y hydrofoil, with a focus on dynamic flow structures such as boundary-layer separation …

This study focuses on the formation and detachment of a leading edge vortex (LEV)
appearing on an airfoil when its effective angle of attack is dynamically changed, inducing …

The prediction of gust loads during atmospheric flight can aid in the design, assessment and
certification of aircraft, and can also enhance the reliability of low-inertia vehicles which are …
