Biological characterization of the skin of shortfin mako shark Isurus oxyrinchus and preliminary study of the hydrodynamic behaviour through computational fluid dynamics.

摘要: This study characterized the morphology, density and orientation of dermal denticles along body a shortfin mako shark Isurus oxyrinchus identified hydrodynamic parameters its through computational fluid-dynamics model. The showed great variability in size, shape, I. oxyrinchus. There was significant higher dorsal ventral areas their highest angular deviations were found lower part mouth between pre-caudal pit second pelvic fins. A detailed three-dimensional geometry from scanned carried out to evaluate properties such as drag coefficient, lift coefficient superficial (skin) friction skin together with flow velocity field, according different roughness coefficients simulating effect denticles. preliminary approach contributed information denticle interactions. As height increased, decreased whereas increased. peaks observed around pectoral
