Abstract
An example fluid pressure reduction device includes a plurality of nested cylinders forming a hollow structure comprising an inner surface and an outer surface. The device also includes a plurality of passageways extending between the inner and outer surfaces through the nested cylinders. At least one of the cylinders includes first apertures substantially differently shaped from second apertures in a second one of the cylinders. At least one of the first apertures has a first wetted perimeter that is greater than a second wetted perimeter of another aperture having the same area as the at least one of the first apertures.
