[Flow past an artificial heart valve with a lens-shaped shutoff element].
An axisymmetric stream-line steady flow of perfect noncompressible liquid through the artificial heart valve with the lens-shaped shut-off element is considered. The liquid motion is described by a continuity equation for which the Dirichlet's problem in the plane of the valve meridional section is stated. Written in the finite differences the differential equation is solved by using a digital computer (ZDBM-220). From the profiles of the liquid flow surfaces built in the plane of the valve meridional section the velocity and pressure patterns for the flow under investigation may be evaluated.
