Abstract

Medical engineering is increasingly deploying nanotechnology and bio-inspired designs in
the 21st century. Motivated by studying the spin coating of bio-nanofluid materials, gyrotactic
bioconvection nanofluid swirling coating flow from a spinning disk to an isotropic permeable
medium is analysed. The balance equations for mass, momentum, thermal, concentration and
microorganism species including blowing effects are transformed into ordinary differential equations
and then the solutions are obtained numerically through MATLAB bvp4c quadrature. These
solutions are further validated with ADM (Adomian decompositions method). Increasing radial
momentum slip reduces the radial skin friction and increasing tangential slip suppresses the
tangential skin friction. Nusselt number, nanoparticle Sherwood number and micro-organism density
number gradient are respectively decreased with increment in thermal slip, nanoparticle mass slip
and micro-organism slip factors. Combinations of bioconvection and nanofluids provide excellent
advantages in designing anti-bacterial and resilient bio-coatings for many devices.
