Geometry optimisation of vertical axis wind turbine with Gurney flap for performance enhancement at low, medium and high ranges of tip speed ratios (2021)
Journal Article

Optimisation of Gurney flap (GF) geometries mounted on a three-straight-bladed vertical axis wind turbine (VAWT) is evaluated with computational fluid dynamics (CFD) solution and Taguchi method, considering the blade rotating effect at three tip spee...

Anatomy of air entrapment in drop impact on a solid surface (2021)
Journal Article

When a drop impacts on a solid surface, a thin air film is entrapped first and later evolves into a spherical air bubble at the center inside the drop. The problem involves several complex physical processes, including two-phase fluid flow interactio... Read More about Anatomy of air entrapment in drop impact on a solid surface.

Near stall unsteady flow responses to morphing flap deflections (2021)
Journal Article

The unsteady flow characteristics and responses of an NACA 0012 airfoil fitted with a bio-inspired morphing trailing edge flap (TEF) at near-stall angles of attack (AoA) undergoing downward deflections are investigated at a Reynolds number of 0.62 ×...

Aerodynamic and aeroacoustic analysis of a harmonically morphing airfoil using dynamic meshing (2021)
Journal Article

This work explores the aerodynamic and aeroacoustic responses of an airfoil fitted with a harmonically morphing Trailing Edge Flap (TEF). An unsteady parametrization method adapted for harmonic morphing is introduced, and then coupled with dynamic me...

U-model-based two-degree-of-freedom internal model control of nonlinear dynamic systems (2021)
Journal Article

This paper proposes a U-Model-Based Two-Degree-of-Freedom Internal Model Control (UTDF-IMC) structure with strength in nonlinear dynamic inversion, and separation of tracking design and robustness design. This approach can effectively accommodate mod... Read More about U-model-based two-degree-of-freedom internal model control of nonlinear dynamic systems.
