RISThree Dimensional RANS Prediction of Gas Side Heat Transfer Coefficients on Turbine Blade and Endwall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a study using 3D computational fluid dynamics (CFD) based on Reynoldsaveraged NavierStokes (RANS) equations to predict turbine gasside heat transfer coefficients (HTC) on the entire airfoil and endwall. ...
The Effects of Vane Showerhead Injection Angle and Film Compound Angle on Nozzle Endwall Cooling (Phantom Cooling)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of airfoil showerhead (SH) injection angle and filmcooling hole compound angle on nozzle endwall cooling (second order filmcooling effects, also called "phantom cooling") were experimentally investigated in a ...
Unsymmetrically Loaded Cylindrical Tank on Elastic Foundation
Publisher: American Society of Civil Engineers
Abstract: The analysis of axisymmetric shells of arbitrary shapes subjected to arbitrary loading has attracted considerable attention. If one considers the Fourier series of the circumference direction of loads and displacements, ...
Turbine Platform Cooling and Blade Suction Surface Phantom Cooling From Simulated Swirl Purge Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the swirl purge flow on a platform and a modeled landbased turbine rotor blade suction surface. Pressuresensitive paint (PSP) mass transfer technique provides detailed filmcooling effectiveness distribution ...
Comparison of Flow and Heat Transfer Distributions in a Can Combustor for Radial and Axial Swirlers Under Cold Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comparison study between axial and radial swirler performance in a gas turbine can combustor was conducted by investigating the correlation between combustor flow field geometry and convective heat transfer at cold flow ...
