“…For the lift coefficient versus Transition point (Xtr) plot, all the aerofoils show a similar down falling trend. [19] has presented the optimization of HAWT by considering different parameters like AOA, aerofoil type, and speed of the wind. The investigators considered various NACA aerofoils namely 4412, 2412, modified 4412, and modified NACA2412 for the analysis using Q-blade software and optimization by using Taguchi method.…”

The current paper demonstrates the design parameters and tolerances for a horizontal axis wind turbine. Here we have adopted one of the DOE (design of experiment) method namely Taguchi method, a traditional approach for designing a robust wind turbine. For optimization purpose, the evaluation and estimation of various problems i.e; constrained as well as unconstrained have been done using Taguchi method. For the derivation of design parameters lift coefficient (CL), drag coefficient (CD) and power coefficient (CP) the L-9 Orthogonal array (OA) comprising of 4 parameters each with three levels (NACA aerofoil type, Mach number, Reynolds number and angle of attack) are considered. Open source Q-Blade designing software is used for determining power, lift and drag coefficients of the wind turbine. The combination of GRA and orthogonal arrays are used for attaining the optimized parameters. In this paper an investigation has been carried out on the specific NACA aerofoils 4412, 4712 and 4421. Among all the aerofoils NACA 4712 has showed the impressive results in terms of maximum lift coefficient of 0.9491and minimum drag coefficient of 0.02601. Also from signal to noise plots it can be inferred that the most influenced parameter for CL and CD is Mach number and Aerofoil for CP.

“…The force which acts on an airfoil, the chord line to the wind direction is the angle of attack (α) and the chord line to the line of rotation is the pitch angle (β) accordingly shown in Figure 1(a) and (b) [13]. The Taguchi is used to optimize the process to make a better-quality product and get more optimal results.…”

“…The simulation and optimization of HAWT rotor power of NACA airfoils (2412 and 4412) using BEM reveals that the most optimal parameter is the NACA 4412-2412 airfoil trailing edges modified at 3° angle of attack and 8m/s wind speed [13]. Airfoil leading edge modification for wind turbine rotors by adding bumps resulted in a higher lift coefficient compared to wind turbines without additional bumps [14].…”

The rotor is one of the vital components of a wind turbine. In the design of the rotor, the expected result is the most optimal power. This purpose study is to optimization of the Horizontal Axis Wind Turbine power of various parameters such as airfoil, angle of attack, and pitch angle. Airfoils (NACA 4412-2412 T.E. mod, NACA 2412-4412 T.E. mod, NACA 4412-2412 L.E. mod, NACA 2412-4412 L.E. mod), angle of attack (0, 2, 4, 6), and pitch angle (0, 1, 2, 3) are the parameter variations used. The simulation method uses BEM (Blade Element Momentum), and the Taguchi for optimization is based on the L16 orthogonal array matrix. The ANOVA has to determine the contribution of each parameter to the HAWT power generated. Simulation and optimization results show that the most optimal parameter was a NACA airfoil 4412-2412 L.E mod, at 0˚ angle of attack and 0˚ pitch angle, with the resulting power reaching 1015780 Watt. The ANOVA analysis shows the airfoil parameter has the greatest contribution to the rotor power of the HAWT compared to the angle of attack and pitch angle.

“…According to the previous work by using javafoil software; comparison between different airfoils to select the appropriate foil used as wings for the submerged glider was done. NACA 0012 was chosen as a hydrofoil section for subsurface wing system according to the results of AoA, lift and drag coefficients [12,13] As the angle of attack is increased, the separation flow region continues moving towards the leading edge. At certain critical AoA at 15 o , the lift coefficient will drop rapidly and drag coefficient will increase rapidly.…”

The underwater gliders are type of autonomous underwater vehicles, which are in their way to be used instead of traditional propellers or thrusters. They are used as submerged gliders or as a part connected to floating hull which is propelled by it. The underwater system depends on different number of hydrofoils (underwater wings) that allow it to glide forward while descending through the water. This paper concentrates on three critical design details: profile of the wings, multiple flapping wings and their angle of attack (AoA), and a method is focused on the mesh generation to predict calm water resistance for the submerged glider system while considering the profile and the maximum rotating angle of the wings and rudder. Flow around submerged wing system model has been calculated at different Froude numbers ranging from 0.1 to 0.6. The grid generator is established for meshing the computational domain with structured hexahedral and unstructured tetrahedral grid. Simulations are carried out using commercial CFD code ANSYS Fluent 19 to calculate calm water resistance of the submerged glider system with different number of hydrofoils. The results conclude that the cambered plate was chosen to design the rudder at 19 o AOA and the hydrofoil NACA0012 can be practically applied in the design of the wings at 15 o AOA from the resistance point of view. In addition, this investigation introduces a new application for CFD calculations in estimating the resistance of the submerged glider system.
