Abstract

Results are given of the numerical solution of the equations which describe in the quasione-dimensional approximation the motion of a fluid in a pipe made of a viscoelastic material with a nonmonotonic S-shaped static characteristic curve. Some possible ways are considered for obtaining simpler models with lumped parameters for such flows. There is a discussion of the application of the theory to the problem of the tone of blood vessels.
