Abstract
The analysis of entropy generation has received notable attention
in the study of nanofluids because the prime objective of nanofluids is to admit high heat fluxes. The entropy production can be utilized to generate the
entropy in any irreversible heat transfer process which is important in thermal
machines. This work presents to explore the fluid transport characteristics and
entropy generation of a tangent hyperbolic nanofluid over a horizontal circular
cylinder with the influence of nonlinear Boussinesq approximation. The dimensionless nonlinear partial differential equations have been solved by using an
implicit finite difference Keller box scheme. The impacts of active parameters
on the flow field like Weissenberg number, power-law index, magnetic field,
mixed convection, Brownian motion, thermal convention, thermophoresis and
radiation are illustrated with graphs and tables. The current results exposed
that the nanofluid velocity enhances for enhancing the mixed convection parameter. Higher values of nonlinear thermal convection parameter declines the
thermal boundary thickness. Total entropy generation decreases for higher values of Eckert number. Isotherms thickness is escalated with increasing values
of radiation parameter.
