Abstract
This paper demonstrates numerical
investigations using analytical algorithms and advanced
computer simulation package to study the performance of a
pumping system and the best angle of attack for a Shape
Memory Impeller. Comparing the analytical algorithm and
simulation, it shows that the best angle of attack is 12 degree at
the outlet angle with respect to the inlet angle. Increasing the
angle of attack from 35 degree to 45 degree at the outlet there
is huge increase in flow rate by 63.47% and slight decrease in
the impeller Torque from 35 degrees to 42 degrees by 0.72%.
This study successfully conceptualised a Shape Memory Smart
Centrifugal Impeller that will increase fluid flow rate through
a given system if the fluid temperature increases above a given
transition temperature using NiTi Shape Memory Alloys was
achieved.
