A model for time-dependent flow in (giraffe jugular) veins: uniform tube properties
1.99 MB 1 downloads
Abstract: Computations are reported for a one-dimensional model of time-dependent flow in collapsible tubes representing long mammalian veins. The tubes are taken to have uniform intrinsic properties and we concentrate...
