Abstract
“Computational fluid dynamics analysis of a modified Savonius rotor and optimization using response surface methodology,” by Haris Moazam Sheikh, Wind Engineering 2017, 41(5), pp. 285–296.
The article contains an incorrectly composed sentence on p.3:
Last full paragraph on page 3, “Mathematical formulation and numerical approach….” should read as:
“Mathematical formulation and numerical approach. Cp and Ct are obtained as functions of shape factor, TSR and overlap ratio-using CFD. Torque is calculated at each instant and is used to calculate Ct and Cp using the relations Ct = Q/V2inASR and CP = Ct·TSR where TSR = ω⋅R/Vin. For unit height, AS = S·1 and aspect ratio = 1/D. The overlap ratio for the rotor is G = m/2R, and Reynolds number is defined as Re=ρuD/μ.”
