The use of photoactivatable fluorophores in the study of turbulent pipe mixing: Effects of inlet geometry

Abstract

The effects of inlet conditions on downstream mixing in turbulent pipe flow have been studied with the use of photoactivatable fluorophores and standard laser-induced fluorescence techniques. The different inlet conditions included both geometry changes and changes in the manner in which the constituents were introduced into the flow. Results indicate that small changes in inlet geometry can greatly affect the downstream mixing rate. Changes in the geometry of the inlet had a greater influence on downstream mixing than did the manner in which constituents were introduced into the flow. Further experiments included a static mixer that was used in conjunction with two different inlet condition..
