Spatial dynamics of blood flow pressure in large vessel corrupted with stenosis is studied. The pressure field was obtained as solution to flow – structure interaction problem using the finite elements. The fact of significant inhomogeneity of the pressure field in stenosed area is confirmed. The accurate analytic model for the pressure mean-squared band width as well as the spacefrequency pressure spectrum model are proposed.
