Observations of flow patterns by electrochemical means

Observations of flow patterns by electrochemical means The Baker technique for visualizing fluid flows consists of generating hydroxyl ions (OH−) in situ in a flowing fluid by electrochemical means. An acid–base indicator is added to the solution, which has been adjusted to an appropriate pH. The local generation of hydroxyl will change the pH locally and hence the color of the indicator will change locally. This technique was introduced in 1966 by D. James Baker. One immediate advantage of this technique is that the tracer is neutrally buoyant. This paper explores the workings of this method in a manner which should give considerable confidence in exactly what is being observed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

The Baker technique for visualizing fluid flows consists of generating hydroxyl ions (OH−) in situ in a flowing fluid by electrochemical means. An acid–base indicator is added to the solution, which has been adjusted to an appropriate pH. The local generation of hydroxyl will change the pH locally and hence the color of the indicator will change locally. This technique was introduced in 1966 by D. James Baker. One immediate advantage of this technique is that the tracer is neutrally buoyant. This paper explores the workings of this method in a manner which should give considerable confidence in exactly what is being observed.
