In a flow, the boundary layer represents a (relatively) thin layer of fluid that is nearest the solid boundary. 87-351 Fluid Mechanics. [ physical interpretation: what are we doing today? ]. The behaviour of the boundary layer is very different from that of the fluid above it. May 11, 10:40 a.m.. It was a beautiful spring morning on the farm when Terry Clark was called over to the silo and told there was a problem — cotton seed in one of the silos had stopped flowing. Thinking it was probably due to a bridging (arching) problem, Terry put on a body harness with a retractable lifeline and prepared to enter the silo to help get the seed moving again. Once inside, he removed the harness so a coworker could use it to enter the silo. Soon after Terry removed the belt, the seed bridge collapsed and he was pulled down. Terry was totally engulfed in cotton seed and died of suffocation. .
