Fluid Dynamic performance of Euplectella aspergillum: drawing inspiration from deep-sea glass sponges for engineering design
ORAL
Abstract
We employ the Lattice Boltzmann Method (LBM) to describe the fluid dynamic field at various Reynolds number, from Re = 100 to Re = 2000, with a space resolution of 0.2 mm, considering the complete geometry of E. aspergillum and four simplified models, derived from the morphology of the deep-sea sponge.
We detail the formation of coherent fluid-dynamic structures downstream the geometries and within the body-cavity, and the role of the sponge skeletal motifs on the formation of such patterns.
The results will have broad repercussions for engineering applications, from the design of aero-naval structures with reduced drag to the realization of novel chemical reactors and slender skyscrapers.
