Modelling the aerodynamics of vertical-axis wind turbines in unsteady wind conditions [PDF]

open access: yes, 2013
Most numerical and experimental studies of the performance of vertical-axis wind turbines have been conducted with the rotors in steady, and thus somewhat artificial, wind conditions - with the result that turbine aerodynamics, under varying wind ...

Unsteady flow behaviour of multi-rotors in ground proximity

open access: yesFlow, 2023
The unsteady flow behaviour of two side-by-side rotors in ground proximity is experimentally investigated. The rotors induce a velocity distribution interacting with the ground causing the radial expansion of the rotor wakes.

Experimental investigation of some aspects of insect-like flapping flight aerodynamics for application to micro air vehicles [PDF]

open access: yes, 2009
Insect-like flapping flight offers a power-efficient and highly manoeuvrable basis for micro air vehicles for indoor applications. Some aspects of the aerodynamics associated with the sweeping phase of insect wing kinematics are examined by making ...

On the use of load-transformation matrices when working with internal wind tunnel balances [PDF]

open access: yesFME Transactions, 2015
Internal wind tunnel balances are often classified by the design as 'force', 'moment' or 'direct-read' balances. Only the direct-read balances can immediately yield the total loads; with other designs, balance-type-specific transformations of actually ...
