Prediction of Laminar-to-Turbulent Boundary Layer Transition in Axial-Flow Turbomachinery.
Abstract
This paper first reviews current analytical studies regarding the laminar-to-turbulent boundary layer transition process, including relevant analysis of laminar separation, and then covers analytical and experimental studies concerning parametric effects on transition pertinent to axial-flow turbomachine blade rows. These include the effects of pressure gradient, freestream turbulence, surface roughness, heat transfer, and combined effects. Finally, the work of various authors who have established data correlations for transition on axial-flow turbomachine blade rows is evaluated. Their predictive equations and charts have been presented as a reference guide for determining the transition region on blades. Additionally, equations for calculating transitional boundary layer growth are presented. (Author)
