220.127.116.11 Flow Resistance
Flow resistance is typically implemented when modeling arterial flow, where the finite element domain only describes a portion of an arterial network . A flow resistance may be imposed on downstream boundaries to simulate the resistance produced by the vascular network with its branches and bifurcations. The resistance is equivalent to a mean pressure which is proportional to the volumetric flow rate , where is the resistance. Using the pressure-dilatation relation (5.17-5), equivalent to , this pressure may be prescribed as an essential boundary condition on the dilatation .
