Computational optimization for the deposition of bioconvection thin Oldroyd-B nanofluid with entropy generation

Abstract The behavior of an Oldroyd-B nanoliquid film sprayed on a stretching cylinder is investigated. The system also contains gyrotactic microorganisms with heat and mass transfer flow. Similarity transformations are used to make the governing equations non-dimensional ordinary differential equat...
