Mathematical Toolbox and its application in the Development of Laboratory Scale Vertical Axis Wind Turbine [PDF]
, 2018 A wind turbine works with the principle of extracting energy from the wind to generate electricity. The power generated is directly proportional to the wind speed available. There are two major types of wind turbine design namely the horizontal and vertical axis wind turbine depending on the orientation of the turbine rotor and its generator.

Modelling yawed wind turbine wakes: a lifting line approach
Journal of Fluid Mechanics, 2018 Yawing wind turbines has emerged as an appealing method for wake deflection. However, the associated flow properties, including the magnitude of the transverse velocity associated with yawed turbines, are not fully understood.

Improved energy production of multi-rotor wind farms [PDF]
, 2019 The multi-rotor (MR) wind turbine concept can be used to upscale wind turbines without increasing the rotor diameter, which can be beneficial for transport, manufacture and design of wind turbines blades. The rotor interaction of a MR wind turbine leads to a faster wake recovery compared to an equivalent single-rotor (SR) wind turbine wake.

The influence of various optimization algorithms on nuclear power plant steam turbine exergy efficiency and destruction [PDF]
arXiv, 2021 This paper presents an exergy analysis of the whole turbine, turbine cylinders and cylinder parts in four different operating regimes. Analyzed turbine operates in nuclear power plant while three of four operating regimes are obtained by using optimization algorithms - SA (Simplex Algorithm), GA (Genetic Algorithm) and IGSA (Improved Genetic-Simplex ...
