Abstract
The bioconvective mixed convection flow has engineered significant applications in various industrial processes, biotechnology systems and biomedical engineering. The objective of current analysis is to analyze a two-dimensional bioconvective flow of non-Newtonian nanofluid in presence of mixed convection effects. The flow is subject to stretched cylinder. The Jeffrey fluid model is retained in order to evaluate the rheological aspects of non-Newtonian material. The motivated bioconvective problem addresses the heat and mass transfer impact in complex systems. The numerical simulations are performed with implementation of finite difference method (FDM). Physical aspects behind variation of parameters are graphically intended. It has been predicted that fluid velocity enhances due to Grashof number and buoyancy ratio parameter. The microorganisms profile declined due to higher Peclet number. The findings are particularly relevant to the design of nanofluidic heat exchangers, bio-convective cooling technologies, microbial fuel systems, and MHD-based polymer processing devices.
期刊介绍:
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
