Περίληψη

Over the past years, several mathematical models have been proposed for the aerodynamic response analysis and power output prediction of wind turbine rotors. Among them, the BEM theory is considered as the current standard for assessing the rotor performance in design and aero-elastic analysis applications, given its ability to obtain remarkably accurate results for a wide range of operating conditions, in a very short period of time. This diploma thesis presents the development of a new Graphical User Interface (GUI) for the support of a BEM analysis software (BEMcode), previously developed in the Turbomachines and Fluid Dynamics Laboratory (TurboLab – TUC) at the School of Production Engineering and Management of Technical University of Crete. The current GUI implementation was accomplished by the utilization of C++ programming language and Qt cross-platform application. The user is able to utilize different data input methods, as well as to visualize and extract the corresponding results. The particular GUI allows for the convenient generation of the preferred airfoils, the calculation of the required aerodynamic coefficients (by incorporating XFOIL solver), the extrapolation of the lift and drag coefficients to the whole 360° range of angles of attack, as well as the definition and visualization of the blade geometry. During the BEM simulation the user is able to include several correction models that increase the accuracy of BEM theory, while the simulation of shrouded or Diffuser Augmented Wind Turbine (DAWT) rotors is also available, through the incorporation of an extended 1D Momentum theory. The accuracy of BEMcode software was successfully assessed against the well-known QBlade software, as well as against numerical and experimental data available in the literature.
