Longitudinal Vortices Inducted in a Stagnation Region by Wakes -- Their Incipient Formation and Effects on Heat Transfer from Cylinders,

Abstract

The horseshoe-like vortices, induced by wakes in the stagnation region of bluff bodies, are proposed as an efficient mechanism for the augmentation of convective heat transfer from a cylindrical body. The first documentation of this flow module is achieved during the course of this study, for single and multiple impinging wakes, with the aid of various visualization methods in both air and water. Quantitative visualization techniques are used to establish the incipient formation conditions for the vortex flow module for single and multiple wakes, and an empirical correlation of the threshold data is achieved.
