Chandler Loop System ®
The Chandler Loop is a suitable dynamic flow model. But it remains only a model. With restrictions and limitations. Don't confuse it with the biological reality:
There is an airbubble and boundaries between air and blood column inside the loop.
Blood is no Newton fluid as most flow calculations simplificate.
Viscosity of blood and the sheer stress are complex corelated parameters.
The fluid movement is simplified to laminar flow conditions.
