Wall Turbulence
Abstract
This research was aimed at understanding turbulence generated at a wall. The goals were to investigate the structure of turbulence in the viscous wall region, to understand how production of turbulence is related to measured structural parameters, to develop models that will allow the computation of velocity and temperature fields, and to explore how the characteristics of wall turbulence are changed by external influences. The principal tools that were used are electrochemical techniques that measure turbulence characteristics in the immediate vicinity of a wall without interfering with the flow, the laser Doppler velocimeter, computer experiments, and pulsed-laser velocimetry. External influences to be studied are imposed flow oscillations, wavy walls and drag-reducing polymers.
