APPLICATION OF VISUALIZING TECHNIQUE IN THE RESEARCH OF ARTIFICIAL VALVE

摘要

With the method above mentioned we have got ideal result in the study of the fluid passing through a artificial valve when it opened. From the velocity vector diagram of the bloodstream passing through the artificial valve Bjork Shiley ( Fig 5 ) we can find that many points at different positions are completely different in velocity. Their motion directions and even the circular movement of the fluid at a certain time are also very clear. It supplies important bloodstream dynamic basis for the designing and improving works of artificial valves. This approach can be used in other fluid studies too .
