His visualizations, performed using smoke, show that eddies in the outer region of the boundary layer are rapidly distorted as they approach the protuberance.
The original platform, about 5 m in diameter, may have been built to enhance a natural protuberance in the bedrock.
The left wrist has a slight protuberance on the inferior side, and the right wrist has a slight protuberance on the superior side.
On the margo dorsolateralis of the right dentary, 15 protuberances are preserved.
The only anterior protuberances are the minute fused antennae and maxillary palpi.
The flow in the immediate vicinity of the leading edge of such a protuberance is very poorly documented and understood.
The cremaster consists of a small protuberance at the tip of the 10th segment, bearing about eight hooked spines.
The protuberances should exert a comensurate repulsion of the flow.
