Vortex breakdown (VB) in unconfined swirling jets occurs as either a bubble form of vortex
breakdown (BVB) or a conical form of vortex breakdown (CVB). This computational study …

Experimental investigations of laminar swirling jets had revealed a new form of vortex
breakdown, named conical vortex breakdown, in addition to the commonly observed bubble …

Vortex breakdown (VB) in swirling jets can be classified as either a bubble (BVB) or a
conical (CVB) form based on the shape of its recirculation zone. The present study …
