Artical Reynolds numbers for pulsatile flow in the circular tube
Klimeš, František ; Kořenář, Josef
The problems of the stability of a laminar pulsating flow have their importance in cardiovascular fluid dynamics. The decelerated flow of blood after a contraction of the left ventricle (in systole) can be laminary even at a considerable high Reynolds' numbers. We presented a description of our experimental equipment and obtained results together with results published by several invesigators. Results indicated that the critical Reynolds number depends markedly on frequency similarity parameter and velocity or volume flow ratio.
