Instantaneous flow field
NettetThe unsteady flow field of a representative fan stage was measured by DLR using hot-wire anemometry. The hot-wire measuring technique allows to determine unsteady … NettetAt larger Womersley numbers, the instantaneous flow field in the stenosed region is found to have a stronger influence on the flow profiles of the previous time levels. The study delineates how an approximation in the assumption of inlet pulsatility profile may lead to significantly different prediction of hemodynamic wall parameters. 1.
