摘要: Abstract Several species of specialized bees possess special structures to store and transport floral oils. By using closely spaced hairs at their back legs, the so called scopa, these can absorb release oil droplets without loss. The high efficiency this process is a matter ongoing research. Based on recent X-ray microtomography scans from bee’s we build three-dimensional geometric computer model. Then, NaSt3DGPF, two-phase flow solver developed Institute for Numerical Simulation, compute micro in scopa Our calculations reveal laminar turbulent air during flight. Furthermore, simulate deformation an droplet due surface tension effects microscopic length scale. results are good agreement with measurements oil-wetted steady state which obtained scans. Both simulations relevant understanding absorption transportation real bee. Due large computational complexity problem, massively parallel computations essential our simulations.
