Abstract
This paper introduces a new data visualization technique for the evaluation of 3D unsteady data using the various terms of the deterministic unsteady vorticity transport equation. The toroidal vortex residing in the inlet cavity of an axial turbine rotor labyrinth is discussed using the proposed technique. Especially, secondary flow effects and the effect of unsteadiness with respect to its contribution to loss generation were investigated. The analysis allowed further insight in flow physics. It was found that the rotational acceleration of the vortex shows a phase shift of one quarter of blade passing period relative to the vortex strength.
