"FLOW IN A$
SCREW PUMP"
Shapemaker has been used here to create the helical coil object
and the case presented makes use of it for the situation when
the rotation of a helix attached to the shaft pumps the fluid.
This case deals with the fluid flow driven by the tangential
movement of screw rotor in a an open ended pipe creating
the pumping effect.
Note that the rotor and coils are treated as solid blockages,
and the rotation is imparted by setting the slide velocity
to a set angular velocity in rad/s. The chosen angular rotation
results in a speed of 1m/s at the surface of the rotor.
