Conclusions

1. Calculation of the stream surfaces during flow past the artificial heart valve with a lenticular shutoff permits finding the distribution of pressures during flow past the valve and determination of the region of increased shear stresses in the flow.

2. An especially marked increase of the velocity of the fluid and decrease of pressure are observed near the edge of the shutoff. Here we should expect maximum shear stresses, which during operation of the valve in the heart can be the cause of mechanical hemolysis of erythrocytes.

3. The region of separation behind the edge of the lens, filled with intense eddies, leads to increased hydrodynamic resistance of the valve installed in the heart, and is also a source of thrombosis.
