Simulation of Mist Film Cooling on Rotating Gas Turbine Blades
Film cooling technique has been successfully applied to gas turbine blades to prevent it from the hot flue gas. However, a continuous demand of increasing the turbine inlet temperature to raise the efficiency of the turbine requires continuous improvement in film cooling effectiveness. The concept of injecting mist (tiny water droplets) into the cooling fluid has been proven under laboratory co...
متن کاملPerformance Evaluation of Simple Aero Gas Turbine Cycle with Transpiration Cooling of Gas Turbine Blades
Aero gas turbine engines have been using mainly film cooling and convection cooling techniques. For operating at high gas temperature amongst different cooling options the transpiration cooling technique has emerged as the most promising technique to improve the gas turbine cycle performance by allowing higher turbine inlet temperatures. This paper investigates the advantages of transpiration c...

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...

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 کاملLarge eddy simulation of turbulent heat transfer in stationary and rotating square ducts
The velocity field and the instability of the flow in a rotating square duct were investigated. The velocity profiles were obtained for Ekman numbers less than 1/16 by combining a linear Stewartson layer solution, a non-linear Ekman layer solution and a local similarity assumption. The transition of the secondary-flow pattern from one pair of vortices to two pairs of vortices was studied with t...
