RISSimplified Approach to Predicting Rough Surface Transition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbine vane heat transfer predictions are given for smooth and rough vanes where the experimental data show transition moving forward on the vane as the surface roughness physical height ...
Modeling of Rough-Wall Boundary Layer Transition and Heat Transfer on Turbine Airfoils
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new model for predicting heat transfer in the transitional boundary layer of rough turbine airfoils is presented. The new model makes use of extensive experimental work recently published by ...
Surface Roughness Effects on External Heat Transfer of a HP Turbine Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: External heat transfer measurements on a highly loaded turbine vane with varying surface roughness are presented. The investigation comprises nine different roughness configurations and a smooth ...
Extended Models for Transitional Rough Wall Boundary Layers With Heat Transfer—Part I: Model Formulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two extended models for the calculation of rough wall transitional boundary layers with heat transfer are presented. Both models comprise a new transition onset correlation, which accounts for ...
