“…All identical structural changes were compared using DMS and LLT simulations, the changes include overall structural changes, sectional modifications along the blade length, bio-additions and add-ons (section 4.4). DMS or [11] Double Multiple Stream-tube is an embedded method within Q-Blade that uses virtual stream tubes which are split up into smaller flow tubes and during 360 o path simulation the turbine blades pass through these tubes, the energy extracted and velocity reduction of the fluid is compared, The DMS rotor and turbine methods uses this to compare the power coefficient, tip speed ratios of the blade, velocity and rotor power.…”

“…LLT or Non-linear laminar turbulent simulation model is another embedded Q-Blade method used for generating wind flow field-based simulation to detect flow distribution and vortices generated from the turbine [11]. For the setup, a 1.5 meter height, 2 meter width and 50 meter length cylindrical mesh domain with an inlet wind field plane perpendicular to the rotor was used, operational points of TSR was selected at 4 and an average RPM of 300 was set based on the regional average wind speeds found as well as the results from X-Foil, The model is kept at an azimuthal angle of 270 o to ensure faster initial cut-in.…”

“…The performance of different aerofoils at different operational loads. The analysis of (NACA 2412) and (SG 6042) aerofoils are done and compared by using Q-Blade software, Alaskari et al [11] have done the design and optimization analysis of SG6043 aerofoil with Q-Blade software and reported that Q-Blade software is reliable to analyse the blades of wind turbines. We need to understand the formulas which govern them and formulas which define the characteristic feature of wind turbines.…”

Performance and efficiency of a Vertical Axis Wind Turbine improved by using a modified turbine blade, derived from biological features, by harness more wind energy. The detailed simulations were carried in Q-blade’s X-foil, Java foil and Sim Scale software at low wind speed with bio-mimicable cambered foil add-ons to different biostructure blades such as Maple seed leaf, Eagle wing. Among these simulations, the Corrugated Dragonfly vein FX 63-137 foil shows improved performance over cambered foils and FX 63-37 itself. The Maple-Wing combined blade structure showed an improved lift-drag ratio with a high coefficient of power.

The use of wind energy has no harmful effects on the environment. This makes it a clean energy that is a real alternative to the problem of nuclear waste management and greenhouse gas emissions. Vertical axis wind turbines have prospective advantages in the field of domestic applications, because they have proven effectual in urban areas where wind flow conditions are intermittent, omnidirectional, unsteady and turbulent. The wind cannot ensure a regular energy supply without optimising the aerodynamics of the blades. This article presents a reminder about wind energy and wind turbines, especially the VAWT type wind turbines and also gives a presentation on the aerodynamic side of VAWT by studying the geometry and aerodynamic characteristics of the blade profiles with the acting forces and also the explanation of the DMS multiple flow tube model. This work also gives the different simulation methods to optimize the behaviour of the blades from the selected NACA profiles; the analysis first goes through the design of the blades by the design and simulation software Qblade which is used to calculate also the forces on the blade and the coefficients of lift, drag and fineness. At the end of this article we have the DMS simulation of the VAWT turbines, by determining the power coefficient and the power collected by the turbine to select the wind turbine adapted to a well characterized site.
