Blood clotting inside the ventricle is one of the biggest problem to be solved for the development of the artificail heart.
Scince the interaction of blood and material take place in the boundary layer, it is very important to eliminate a low blood flow area or a stagnation point close to a wall for the prevention of thrombus formation in the blood chamber.
Employing flow visualization technique, so called dye-washout method, we studied how in tegral picture of the boundary layer flow was affected by the parameters as follows; installed position and angle of inlet or outlet conduit, the orientation of the valve, and the shape of the blood chamber. Thirteen different pump housings were tested in this experiment. According to the results of this experiment, two pump designs which may have no clot formation inside the blood chamber were presented.
