heal.abstract	The flow field around a time-dependent 3-D asymmetric tube constriction was studied and comparisons were made with the corresponding 2-D case. Both experimental (LDV-PIV) and numerical (finite volume) tools were employed for Re<1000, St<0.3 and 50% maximum passage reduction. The basic features of the flow were 3-D separation and reattachment, vortex generation especially after the middle of the cycle (max. constriction), and vortex destruction before the end of the cycle. The snake-type shape of the streamlines, known from the 2-D case, was not observed on the symmetry plane of the examined flow due to the secondary flow action. (C) 2003 Elsevier Ltd.
