“…The BEMT-based analyser WTSim is capable of simulating both constant and variable speed wind turbines with conventional and non-conventional blades (e.g. telescopic blades, blades equipped with microtabs and trailing edge flaps, swept back blades and adaptive blades) and it has a built-in simulator for the control systems [42,43]. Similar to blade aerodynamic load, weight and centrifugal forces are also functions of operating conditions as well as the blade geometry and structural characteristics.…”

Multiobjective optimisation and integrated aerodynamic-structural design of wind turbine blades are emerging approaches, both requiring significant number of high fidelity analyses. Designer-in-theloop blade modelling and pre/ post-processing using specialised software is the bottleneck of high fidelity analysis and therefore a major obstacle in performing a robust optimisation, where thousands of high fidelity analyses are required to find the optimum solution. Removing this bottleneck is the driver for the development of WTBM, an automated wind turbine blade modeller. WTBM takes parameters defining the blade and its operating condition as inputs and generates preprocessor, solver and post-processor APDL files required by ANSYS for high fidelity analysis. The inputs can be generated automatically within an optimisation process, hence so can be the APDL files, allowing a fully automated optimisation in which any of the parameters which are required to define the size, topology, structure and material of a blade to be treated as a design variable. The solver parameters will be also updated automatically as necessary. The performance of WTBM-ANSYS in conducting hundreds of automated high fidelity analyses within an optimisation process is shown through multiobjective structural design and multiobjective integrated design case studies.

In this study, in addition to the recent advances and tendencies in wind turbine technology around the world, the progress of commercial wind turbine technology installed in Turkey was also thoroughly examined. In this respect, several metrics for installed wind turbines including number of turbines, installed power capacity (MW), mean rated capacity (MW), mean rotor diameter (m), mean specific power capacity (W/m2), and mean hub height (m) have been obtained between the years of 2011 and 2019. According to the obtained results, the mean rated capacity of Turkey’s annual installed wind turbines advanced from 1.86 MW in 2011 to 3.52 MW in 2019. However, the mean specific power of yearly installed wind turbines declined from 423.7 W/m2 to 314.1 W/m2. Outcomes revealed that the growth in the size and the reduction in the specific power have contributed to the tendency of higher power outputs, and wind turbine capacity factor and power generation capacity have been on the rise in Turkey. In time, wind turbines with greater rotor diameters and hubs started to show up more observable on land. For that purpose, the proposed solution to regulate turbine visibility during site selection is the potential visibility model (PVM), which is meant to be used as an auxiliary variable.

“…A detailed analysis of blades for the flight vehicles is more crucial since the aerodynamic performance will be affected because of the presence of an unsteady loading such as different wind conditions [19]. These unsteady loads causing the instability over the airfoils can be suppressed or mitigated thanks to material of airfoil [20][21][22] or active-passive flow control techniques [23][24][25][26].…”

This study ensures experimental and numerical investigation of different airfoils to observe and understand how camber ratio affects the flow characteristics over surface of different airfoils. Experimental results in the previous studies were used while the numerical study was performed for present investigation. Reynolds numbers based on the airfoil chords were 1x10 5 and the angle of attack of 8°. Instantaneous voltage output data were used in order to detect transition location for NACA 4412, oil surface visualization experiments were presented for NACA 2415. In the numerical analysis, values of u/U∞ and turbulent kinetic energy were presented for NACA 4415 airfoil. The experimental results denoted that the change of camber ratio and thickness significantly affected the flow phenomenon such as boundary layer separation or formation and progress of the laminar separation bubble. The long bubble was clearly observed with accumulation of pigments at oil-flow measurement experiment. By increasing the camber ratio with the use of NACA 4412 airfoil, the long bubble turned into the short bubble. Briefly, not only the progress and formation of laminar separation bubble was being affected, but also the onset of transition point was obviously influenced by changing of camber ratio.
