RISHeat Transfer Measurements in an Internal Cooling System Using a Transient Technique With Infrared Thermography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a transient method for measuring heat transfer coefficients in internal cooling systems using infrared thermography is applied. The experiments are performed with a twopass internal cooling channel connected ...
Combined Experimental/Numerical Method Using Infrared Thermography and Finite Element Analysis for Estimation of Local Heat Transfer Distribution in an Internal Cooling System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present study a method for estimating local heat transfer distributions of internal cooling systems is described. Experimental data and finite element analysis are applied for this method. The investigations considered ...
Effect of the Biot Number on Metal Temperature of Thermal Barrier Coated Turbine Parts—Real Engine Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For numerous hot gas parts (e.g., blades or vanes) of a gas turbine, thermal barrier coating (TBC) is used to reduce the metal temperature to a limit that is acceptable for the component and the required lifetime. However, ...
The Effects of Ribs and Tip Wall Distance on Heat Transfer for a Varying Aspect Ratio Two Pass Ribbed Internal Cooling Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Internal cooling channels with differing aspect ratios are typically found in gas turbine blades due to the varying thickness of the blade from the leading to trailing edge. These serpentine passages often contain several ...
