In their report, the astronomers said the telescopes detected a radial flow of the tracer molecules, arising primarily from the outer parts of the collapsing cloud and extending in about half of the cloud's radius.

A single peripheral exhaust port routed hot gas through the coolest parts of the housing, and engine coolant flowed axially rather than the radial flow used by NSU . A bit of oil was mixed with the intake charge for lubrication.

Despite the generally higher volume fraction of rays in hardwoods ( typically 15 % of wood volume ), the rays are not particularly effective in radial flow, nor are the pits on the radial surfaces of fibres effective in tangential flow ( Langrish and Walker, 1993 ).
