An Approach for the Analysis of Collapse Onset in Elastic Tube Flows

An experimental study conducted for the determination of the onset of collapse of an elastic tube of a Starling resistor conveying air is presented herein. The collapse was induced under the action of external pressure p e applied to the tube walls. The influence of length L , thickness h , and modu...

Zusammenfassung:An experimental study conducted for the determination of the onset of collapse of an elastic tube of a Starling resistor conveying air is presented herein. The collapse was induced under the action of external pressure p e applied to the tube walls. The influence of length L , thickness h , and modulus of elasticity E of the tube on collapse were determined by using a variety of silicone rubber and latex-Penrose tubes. The experiments were conducted under the presence of constant upstream head with the absence of a longitudinal strain of the tube in a range of flow Reynolds number ( Re ) 16750
