Simulating Cooling Injection Effect of Trailing Edge of Gas Turbine Blade on Surface Mach Number Distribution of Blade
In this research, a gas turbine blade cascade was investigated. Flow analysis around the blade was conducted using RSM and RNG.K-ε turbulence modeling and it is simulated by Fluent software. The results were considered for the cases as Mach number loss at the trailing edge of blade caused by vortexes that were generated at the end of blade. Effect of cooling flow through the trailing edge on th...
متن کاملModel Predictive Control of Trailing Edge Flaps on a Wind Turbine Blade
Trailing Edge Flaps on wind turbine blades have been studied in order to achieve fatigue load reduction on the turbine components. We show in this paper how Model Predictive Control can be used to do frequency weighted control of the trailing edge flaps in order to reduce fatigue damage on the blade root. The design model is based on a modal model of the blade structure and a steady state aerod...
متن کاملExperiments Concerning the Effect of Trailing-Edge Thickness on Blade Loss and Turbine Stage Efficiency
Theoretical assessments of the influence of trailing-edge thickness on turbine blade loss coefficients are reviewed and compared with the results of a cascade tunnel investigation. Tests on a single-stage turbine indicate that efficiency is much more sensitive to stator blade trailing-edge thickness than simple estimates woul d indicate, but rotor blade thickness effects on efficiency are in li...
متن کاملTurbine Blade Tip Cooling and Heat Transfer
ii ACKNOWLEDGEMENTS Behind every success, there is inspiration or support of at least one person. In my case, it was a group of people including my mentor, my family, and my friends. First of all, I would like to thank Dr. Srinath Ekkad for his guidance, wisdom, and financial support. I do not think many advisors would go to the lab to help his student running an experiment. Whenever I had any ...
متن کاملAn experimental investigation on the trailing edge cooling of turbine blades
ational Laborator 016/j.jppr.2012.10 thor. [email protected] r responsibility o ronautics, China. Abstract An experimental study was conducted to quantify the flow characteristics of the wall jets pertinent to trailing edge cooling of turbine blades. A high-resolution stereoscopic particle image velocimetry (PIV) system was used to conduct detailed flow field measurements to quantitatively visua...
