    Description / Table of Contents: Résumé La stabilié du mouvement oscillatoire libre d'un fluide pesant et visquex dans un tube en U est étudiée en utilisant une analyse linéaire. Une méthode développée précédemment pour l'étude de la stabilité de l'écoulement instationnaire de Couette entre deux cylindres coaxiaux, est étendue à cet écoulement pseudo-périodique. Les résultats théoriques obtenus confirment pleinement de précédentes observations expérimentales.
    Notes: Abstract Stability of the free oscillatory flow in a U-shaped tube is considered by the use of a linear stability analysis. A previous initial-value problem approach concerning the stability of time-dependent rotational Couette flow is extended to this pseudo-periodic flow. The theoretical results obtained are in good agreement with experimental observations.

    Notes: Abstract A physical model is developed for the simulation of the left heart and systemic circulation. The simulator includes a transparent and compliant ventricle pumping into an arterial model. The ability of the system to reproduce thein vivo conditions accurately is demonstrated by quantitative comjcarisons with physiological pressure and flow waveforms. As an example of application, flow patterns within the ventricle obtained by visualisation techniques and ultrasonic Doppler velocimetry are presented. Its versatility makes the system an essential tool in cardiovascular flow dynamics.
