Saha and Celata Nanoscale Research Letters 2011, 6:344 NANO REVIEW Open Access Advances in modelling of biomimetic fluid flow at different scales Sujoy Kumar Saha1* and Gian Piero Celata2 Abstract The biomimetic flow at different scales has been discussed at length. The need of looking into the biological surfaces and morphologies and both geometrical and physical similarities to imitate the technological products and processes has been emphasized. The complex fluid flow and heat transfer problems, the fluid-interface and the physics involved at multiscale and macro-, meso-, micro- and nano-scales have been discussed. The flow and heat transfer simulation is done by various CFD solvers. | Saha and Celata Nanoscale Research Letters 2011 6 344 http content 6 1 344 o Nanoscale Research Letters a SpringerOpen Journal NANO REVIEW Open Access Advances in modelling of biomimetic fluid flow at different scales Sujoy Kumar Saha 1 and Gian Piero Celata2 Abstract The biomimetic flow at different scales has been discussed at length. The need of looking into the biological surfaces and morphologies and both geometrical and physical similarities to imitate the technological products and processes has been emphasized. The complex fluid flow and heat transfer problems the fluid-interface and the physics involved at multiscale and macro- meso- micro- and nano-scales have been discussed. The flow and heat transfer simulation is done by various CFD solvers including Navier-Stokes and energy equations lattice Boltzmann method and molecular dynamics method. Combined continuum-molecular dynamics method is also reviewed. Introduction Human knowledge is getting enriched from the four billion years worth of R D in the natural world of plants and animals and other lower level living creatures and microorganisms which have evolved through the ages to nicely adapt to the environment. Man has now drawn his attention to soil creatures like earthworms dung beetle sea animals like shark and plants and trees like lotus leaf and pastes like termites. In the nature we see examples of effortless and efficient non-sticking movement in mud or moist soil high-speed swimming aided by built-in dragreduction mechanism water repellant contaminant-free surface cleaning mechanism and natural ventilation and air conditioning 1-8 . By nature feather of the penguin shows staying warm naturally Figure 1 4 . The leaf of the lotus is hydrophobic to the extent that water running across the surface of the leaf retains particles of dirt caused by a thick layer of wax on the surface and the sculpture of that surface Figure 2 9-11 . This forces the droplets of water to remain .
