Abstract [en]

In this study a series of steady flow in vitro experiments are described in which important hydrodynamic factors, including pressure drop, separation, and turbulence, are considered for tubes which are locally constricted. Both axisymmetric and nonsymmetric plastic models, having different area ratios and lengths of constriction, were used in the experiments. Data were obtained for Reynolds numbers varying from approximately 100–5000. The region of separated flow was investigated and critical Reynolds numbers for transition to turbulent flow were measured using hot-film probes. Results of tests show strong influence of geometry, both the size and shape of stenosis, on flow characteristics.
