“…For turbulence modeling, the k À v SST model is used. The k À v SST turbulence model is chosen because of the capability of this model for capturing the flow structures in oscillating domains (Ahmadi et al, 2009;Ol et al, 2010;Castelli et al, 2011;Rival et al, 2011;Kuang et al, 2021). Besides residuals that show the convergence criteria in CFD problems, the velocity and pressure values are other parameters that are confirmed the convergence of the steady simulation (Balduzzi et al, 2016;Tahani et al, 2016).…”

“…However, further downstream (x = 4D, Figure 17), the effect of turbulent flow on dual VAWTs is more apparent in the velocity distribution. The lower velocity deficit under turbulent flow compared to smooth flow can be explained by the dissipation of the wake caused by the higher mixing with the surrounding wind stream which can lead to faster wake recovery [23]. Figure 18 and Figure 19 show the turbulence intensity measured in the wake at 1D downstream of the paired VAWTs taken at the optimal tip-speed ratio for smooth (I u = 0.35%) and turbulent flow (I u = 5.63%) respectively.…”

“…As far as we know, previous works have only focused on the effect of turbulence on an isolated VAWT, but no previous research has investigated the effect of turbulence on a pair of H-type Darrieus VAWTs experimentally. However, the improvement of the total power output of dual VAWTs in a tandem arrangement under high degree of turbulence was proved numerically [23].…”
