“…Tu    (8) proposed by Mayle [4]. The effect of wall roughness on the transition onset was expressed by the correlation   (9) However experimental data of Jonáš et al [20] and Pinson and Wang [21] show that the wall roughness influences the transition even for k s +  5. Therefore a modification of the correlation according to Boyle and Stripf [6] was proposed in the form…”

The contribution deals with the simulation of the laminar/turbulent transition on a rough wall. The algebraic transition model taking into account wall roughness according to Straka and Příhoda [8] was further extended for the effect of short rough strip near the leading edge. The proposed correlation was tested by means of incompressible flow over a flat plate covered by sand paper and around the NACA 0012 airfoil with a rough strip near the leading edge. The agreement with experiments is appropriate nevertheless the applicability of the correlation is limited due to the lack of relevant experimental results.

“…Pitch control and fixed pitch mechanisms have also been the subjects of investigations (Boorsma & Schepers, 2016;Farouk & Gawad, 2013;Leroy et al, 2016;Neammanee, Sirisumrannukul, & Chatratana, 2010;Strom, Brunton, & Polagye, 2016;Vijae, 2011).

The research on three dimensional (3-D) wind turbine blades has been introduced (Sutrisno, Prajitno, Purnomo, & B.W. Setyawan, 2016). In the current experiment, the 3-D wind turbine blades would be fitted with helicopter-like blade tips and additional fins to the blade hubs to demonstrate some laminarizing features.It was found that additional helicopter-like blade tip to the turbine blade creates strong laminar flows over the surface of the blade tips. Supplementary, finned hub, fitted to the blade body, creates rolled-up vortex flows, weakens the blade stall growth development, especially for blades at high-speed wind. A proposed mathematical form of modified lifting line model has been developed to pursue further 3-d blade development study of 3-d wind turbine blade.Rolled up vortex effects, developed by finned of the base hub, has been acknowledged could demolish the turbulent region, as well as laminarize the stall domain to intensify the induced wind turbine blade lift.

“…Some researchers analyzed subsonic airfoil sections employing the numerical shape for efficiency and effectiveness. Rahimi et al, compared experiments with CFD and investigated the validity of the BEM for the HAWT simulation in complicated load matter [19][20][21][22][23][24][25][26]. Blade design, and efficiency and effectiveness of winglets via rotor blades showed their related optimized geometries.…”

Dimensional Analysis of Power Prediction of a Real-Scale Wind Turbine Based on Wind-Tunnel Torque Measurement of Small-Scaled Models

A preliminary study of a horizontal-axis wind turbine (HAWT) design is carried out using a wind tunnel to obtain its aerodynamic characteristics. Utilization of data from the study to develop large-scale wind turbines requires further study. This paper aims to discuss the use of wind turbine data obtained the wind-tunnel measurements to estimate the characteristics of wind turbines that have field size. One should measure the torque of two small-scale turbines inside the wind tunnel. The first small-scale turbine has a radius of 0.14 m, and the radius of the second small turbine is 0.19 m. Torque measurement results from both turbines were analyzed using the Buckingham π theorem to obtain a correlation between torsion and diameter variations. The obtained correlation equation was used to estimate the field measurement of turbine power with a radius of 1.2 m. The resulting correlation equation can be applied to approximate the energy generated by the turbine using the size of the field well in the operating area and the tip-speed ratio (λ) of the turbine design.
