An Experimental Investigation of the Effect of Adverse Pressure Gradient on Vortex Breakdown.

Abstract

The results of an experimental investigation of the effect of adverse pressure gradient on the vortex breakdown phenomenon in a diverging tube are presented. Adverse pressure gradient was found to be as significant in determining the breakdown position as were the previously known parameters of Reynolds and circulation numbers. An approximate momentum analysis for predicting the vortex breakdown position was carried out which appears to hold promise as a breakdown predictor. (Modified author abstract)
