Characteristics of the flow around two circular cylinders arranged in tandem. I
Abstract
The characteristics of the flow around two cylinders arranged in tandem is experimentally investigated for a range of Reynold's numbers from 8,700 to 52,000 and spacings between the axes of the cylinders of 1.03 to 5.0 L/d where d is the diameter of the cylinder. Up to spacings of L/d = 3.5 where the quasi-stationary vortices are formed between the cylinders, changes of the flow structure around the two cylinders were observed at spacing 1.1, 1.6, 2.3, and 3.1 L/d with dependence of Reynold's number observed between 1.1 and 2.0 L/d. A classification and series of sketches of the flow patterns are provided.
