Experimental study of muscular draining. (Étude expérimentale du drainage musculaire.) (French) Zbl 1349.74261

Summary: We present an experimental setup representing muscular draining in the lower leg. A collapsible tube is placed vertically in a hermetic chamber connected to a variable pressure tank. With the help of electrovalves we study a draining corresponding to walking. When the external pressure is raised a phenomenon of flow limitation appears and the draining time is very long. We also present numerical simulations showing that a critical passage subcritical supercritical originates the flow limitation.
