Abstract
In this paper we present a study of the post valvular flow field on a new cardiovascular simulator including an elastic model of the aortic arch. Transverse and vertical two-dimensional velocity measurements are performed with an ultrasonic velocimeter. Two prosthetic heart valves are tested in the aortic position. The behaviour of the velocity vectors patterns during one pulsatile cycle is one of the most striking features of the flow.
摘要
在本文中，我们展示了一项关于新型心血管模拟器上瓣膜后流场的研究，该模拟器包括主动脉弓的弹性模型。使用超声测速仪进行横向和垂直二维速度测量。在主动脉位置测试了两种人工心脏瓣膜。一个搏动周期内速度矢量模式的行为是血流最显著的特征之一。
