Encara no tenim significats per a "helical volute".
1A similar tendency in vane height was observed by varying the helical volute pitch.
2The parametric study was performed varying the vane height, vane width and helical volute pitch.
3In distribution of pressure, negative pressure was found near the entrance of the inlet helical volute.
4The best helical volute-pitch size is considered to be between 1.5 and 2 times the vane width.
5This shunt flow is thought to be improved by redesigning the inlet and outlet helical volutes.
6The HFP consists of the multi-vane impeller involving rotor magnets, a motor stator and pump housing having double- helical volutes.
7Since the helical volutes are formed at both sides of the impeller, blood flows with a helical flow pattern inside the pump.
