Available in PDF, EPUB and Kindle. Book excerpt: The mean velocity field in the boundary layer and the streamwise and spanwise distributions of heat transfer coefficient have been measured on a concave wall in the presence of naturally-generated Görtler vortices, with and without a preceding flat wall. In near-zero pressure gradient, enhancement of the streamwise-averaged heat transfer above flat surface levels was associated with the attainment of a Görtler number of around ten, as found in previous experiments in a different flow facility with higher wall curvature, but occurred before the onset of severe distortion in the velocity profiles. Velocity gradient parameters K of 0·20 × 10−6 and 0·75 × 10−6 resulted in a more regular vortex structure, with spanwise averaged heat transfer reaching two to three times predicted levels. At K = 1·8 × 10−6, vortex amplification was suppressed to such an extent that no significant heat transfer enhancement took place. Comparison of measured Stanton numbers with those derived from skin friction factors (obtained from velocity profiles) suggested that the heat transfer enhancement is not simply a result of fuller velocity profiles in vortex downwash regions.

Download or read book Heat Transfer and Flow Structure in End-Wall Boundary Layers written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical, numerical, and experimental stndies have documented the flow development and surface heat transfer for several three dimensional end-wall flows, and indicate the presence of highly unsteady vortex formation within the end-wall boundary layer. This vortex formation process leads rapidly to the evolution of three dimensional separation effects which have a profound influence on the surface heat transfer. Analysis of the three dimensional behavior indicates the presence of persistent and strong interactions between the end-wall boundary layers on both the surface and the side-wall boundary layers of the obstacle. A detailed series of Navier-Stokes calculations have been carried out for a vortex-induced motion similar to that encountered in turbulent boundary layers. As the Reynolds number is increased, a new type of instability associated with surface layer separation was found which leads to brealmp of the surface layer. Experimentally, laminar approach flows always develop discrete, periodic necklace vortices in the junction region, whereas a turbulent approach yields a dominant necklace or horseshoe-shaped vortex that moves chaotically. Examinations of the complex fluid/heat transfer processes using PIV and thermochiomic liquid crystals shows that these junction vortices undergo very strong surface interactions, which creates strongly focused "eruptions" of surface fluid; these studies show a direct correlation between the eruptive processes and local regions of high heat transfer.
