Experimental Investigation of the Characteristics of Flow About Curved Circular Cylinders

摘要

The flow and the associated forces on curved circular cylinders, at Reynolds Numbers between 10,000 and 1,000,000, were investigated. The shape and normal force distribution of a flexible curved cylinder were found. Flow visualisation tests and pressure surveys were made on rigid curved cylinders. A comparison was made with earlier results for infinite straight cylinders inclined to the flow. It is concluded that the curvature of a cylinder has a significant effect on the flow and pressure in the wake, and must be considered in the prediction of the aerodynamic forces on such a cylinder.
