Implicit and Explicit Sensitivities for Optimization of Cooled Turbine Blades
The partial derivatives of field variables (temperatures, temperature gradients, thermal conductivity, heat sources. etc.) and boundary values (heat fluxes, heat transfer coefficients, heat radiation, etc.) with respect to the perturbations of the boundary conditions and geometry are very useful when performing a parametric study of a particular design. These partial derivatives are called desi...
متن کاملNew Technologies for Modeling of Gas Turbine Cooled Blades
In contrast to existing methods which do not take into account multiconnectivity in a broad sense of this term, we develop mathematical models and highly effective combination (BIEM and FDM) numerical methods of calculation of stationary and cvazistationary temperature field of a profile part of a blade with convective cooling (from the point of view of realization on PC). The theoretical subst...
متن کاملAero-thermal-elasticity-materials Optimization of Cooled Gas Turbine Blades: Part I
The first lecture in this two-lecture sequence provides background and general concepts. The second lecture provides practical examples. The objective of these two lectures is to provide a modular design optimization tool description that will take into account interaction of the hot gas flow-field, heat transfer in the blade material, internal coolant flow-field, stresses and deformations of t...
متن کاملSampe Europe Conference & Exhibition Advanced Ultrasonic Ndt Techniques for Inspection of Wind Turbine Blades
This paper presents the development of inspection strategies dedicated to the quality insurance of the wind turbine blade manufacturing process and in particular the inspection of the adhesive bondlines. Ultrasonic testing is recognized as a technique that can provide valuable information about the structure. Porosity, dry area and delamination can be detected and characterized in laminates. La...
متن کاملA feasibility study of a computer-based wind turbine blades surface flaws inspection method
Visual inspection is widely used to improve the reliability of in-service products such as wind turbine blades (WTBs), aircraft surfaces, and bridges. Lowering costs by reducing maintenance hours and increasing labor safety, decreasing production and service downtimes, promoting high accuracy inspections as well as making early repair are motivating factors for having reliable visual inspection...
