Near-wake analytical yaw models: A wind tunnel validation

Craig Thompson, Kevin Gouder, J. M. R. Graham

Abstract Analytical wake models are vital in the development of wind farms due to their low computational cost. While research has historically focused on the far-wake region, accurately predicting the near-wake has become increasingly important for understanding interactions with transmission lines, bird …

Biomechanics of the slingshot spider and its three-dimensional web

D.J.N. Limebeer, J. M. R. Graham

A three-dimensional model for the release dynamics of a category of orb web spiders is developed. The web response depends on the material properties of the web silk and its geometric layout. A detailed aerodynamic damping analysis is provided for webs operating …

Analytical yaw models: a two-dimensional comparison

Craig Thompson, Kevin Gouder, J. M. R. Graham

Abstract. Analytical wake models are essential for wind farm design and control. However, they often lack validation beyond scale data. This study compares six, two-dimensional yawed wake models which include single-Gaussian, super-Gaussian, lifting line, and vortex sheet methods. An additional double-Gaussian model …

Turbulence distortion and blockage in the induction zone of a horizontal axis turbine

Kevin Gouder, Ian Milne, J. M. R. Graham

Wind tunnel measurements of the incident turbulent velocity fields and axial forces on a horizontal axis turbine and porous disc analogues are reported. The models were tested in both a simulated atmospheric boundary layer (ABL) and in grid turbulence, allowing for a …

Feasibility study of using bench-scale centrifugation for segregation and consolidation behaviour of oil sands tailings products

Chee K. Wong, Tianquan Hu, J. M. R. Graham, R.C.K. Wong

Fluid fine tailings (FFT) are a by-product of the process used to extract bitumen from surface-mined oil sands in Alberta, Canada. One of the FFT reclamation techniques involves mixing centrifuged FFT with coarse sand tailings to form non-segregating tailings (NST). While NST …

Vortex force map for incompressible multi-body flows with application to wing–flap configurations

Yinan Wang, Xiaowei Zhao, J. M. R. Graham, Juan Li

The vortex force map method for incompressible viscous flows with multiple bodies is derived in this work. The method breaks the fluid force into inertial, vortex-pressure, viscous-pressure and skin-friction components, and it could be used to analyse the fluid dynamic forces on …

Effects of combination motions on hydrodynamic forces induced on bodies in the sea

J. M. R. Graham, Yuling Zhao, Chuanqing Zhou, M Downie

The paper examines two types of flow around long bodies with a range of cross-sections from circular to square. The first situation consists of oscillatory flows having two components at right angles to one another with a range of frequency and amplitude …

An experimental and numerical study of the resonant flow between a hull and a wall

Ian Milne, Olivier Kimmoun, J. M. R. Graham, Bernard Molin

The wave-induced resonant flow in a narrow gap between a stationary hull and a vertical wall is studied experimentally and numerically. Vortex shedding from the sharp bilge edge of the hull gives rise to a quadratically damped free surface response in the …
