Combined genetic algorithm and response surface methodology‐based bi‐optimization of a vertical‐axis wind turbine numerically simulated using CFD

Energy Science &Engineering, Volume 12, Issue 10, Page 4532-4548, October 2024.
The optimum values of moment and lift force for a vertical axis wind turbine were determined by a multi‐objective optimization methodology including response surface methodology (RSM), computational fluid dynamic (CFD), Non‐Dominated Sorting Genetic Algorithm (NSGA‐II), and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).

A Novel Surrogated Approach for Optimizing a Vertical Axis Wind Turbine With Straight Blades

Wind Energy, Volume 27, Issue 9, Page 953-974, September 2024.
ABSTRACT Vertical axis wind turbine (VAWT) has a rotating axis perpendicular to the wind direction. This type of wind turbine that is suitable for urban environments has low wind direction dependency and noise. In this research, a novel surrogated approach for optimizing a VAWT is proposed, used, tested, and verified, which is not reported in ...

Mitigating thermal stratification in lakes/reservoirs through wind‐powered air diffusers

Water Environment Research, Volume 96, Issue 9, September 2024.
A new wind‐powered artificial mixing system is designed and tested for various Savonius rotor combinations. The three‐stage 60° phase shift Savonius rotor demonstrated the best performance of turbine efficiency. The four‐stage Savonius rotor with a 45° phase shift connected to a single‐pump system achieved the highest destratification efficiency at 95%.
