초록

For the characteristic assessment of biomimetic shark skin structure pattern for engineering applications, we conducted the elastic hydrodynamic lubrication analysis for the shark skin surface pattern. The shark skin surfaces with roughness are generated numerically in the similar size with real shark skin scales. For the spherical contact on the generated shark skin surface with two different flow directions which are transversal and longitudinal, 3-dimensional elasto-hydrodynamic lubraction analysis are carried out. The result of the longitudinal flow which are similar with the flow of shark skin shows more beneficial effects with lower pressure and less sensitive effect with surface roughness.
