Numerical investigation of airflow through a Savonius rotor [PDF]

Wind Energy, 2013
ABSTRACTThe aim of this report is to present a model of a rigid‐rotor system based on computational fluid dynamics (CFD), which is applied on a vertical axis wind turbine (VAWT) research. Its originality results from the use of the average value of the variable rotational speed method taken in a periodic steady‐state (PSS) of the VAWT rotor instead of ...

Comprehensive study of vortices interaction and blades height effect in a Darrieus vertical axis wind turbine with J‐type blades

Energy Science &Engineering, Volume 12, Issue 10, Page 4371-4393, October 2024.
This study utilizes a 3D numerical analysis to examine the influence of different vortices generated on turbine efficiency with straight and J‐type blades. The numerical simulation of this study employs the Reynolds‐averaged Navier–Stokes equations and ‎sliding ‎mesh techniques ‎to model the rotational motion of blades more accurately about the turbine
