Residence Time Distribution at laminar pulsatile flow in a straight pipe

Popis výsledku v původním jazyce

This paper deals with the problem of theoretical identification of residence time distribution characteristic of a straight pipe at laminar pulsatile flow. The analysed case is restricted not only to the laminar flow regime but also to the case when diffusion of tracer can be neglected when compared with convection. This situation is typical for micro-apparatuses (e.g. fluidic elements) and also for flow in large arteries. Residence time distribution based upon velocity profiles at pulsatile flow of Newtonian liquid in a rigid pipe (Womersley) will be derived theoretically and results are compared with the well known results for constant flow rate. The significant quantities, i.e. the first time of detection and the mean residence time, are followed. The second part of this contribution is aimed to the stimulus response experimental techniques using tracers. The principal problem related to laminar and convection dominated pulsatile flow is indicated.
