Title

Evaluating The Effect On Component Cooling And Thermally Generated Stress Caused By Variation Of Internal Heat Transfer Coefficients Through An Uncertainty Quantification

Abstract

Through the use of probabilistic design a process is developed to simulate variation of internal heat transfer coefficient. It is then applied to a non-rotating blade component, internally cooled through mutli-pass serpentine channels. While keeping the external parameters constant the internal heat transfer coefficient variation is then simulated in regions of high uncertainty, such as tip and hub turns, and the effect on the thermally generated stress of the airfoil is evaluated using ANSYS. Through a change in heat transfer coefficients the fluid temperatures will also vary, which is captured in the integrated fluid dynamics model. Although other cooling features such as film cooling, as well as any impingement flow is not considered in this study, the effects on the fluid dynamics model are incorporated through advection and fluid elements.
