This paper deals with fluid mechanical problems encountered in eight years
of developmental studies on a centrifugal blood pump with magnetically susp
ended impeller. The main results of the investigation are as follows. The i
mpeller disk friction is dominant among all the power losses; the magnetica
lly suspended impeller with radial straight vanes is the most stable. Motor
current depends on blood viscosity and flow rate. Consequently, the flow r
ate and pressure difference can be estimated by self-sensing without any ne
ed for flowmeter and pressure transducers.
