- •
Accurate 3-D spacer geometry was obtained from X-ray computed tomography (CT) scans.
- •
Filaments of industrial spacers have a highly variable cross-section size and shape.
- •
CFD simulations were in close agreement with experimental pressure drop data.
- •
Spacer strand shape significantly influences the power input, shear and friction.
- •
A new spacer geometry with alternating strand thickness was evaluated.
