This analysis deals with the significances of bio-convection for the Carreau nanofluid flow over a stretched cylinder. The investigation is modified by suggesting the contribution of melting phenomenon and chemical reaction are also addressed. The thermal flow analysis is inspected in view of convective Marangoni boundary constraints. The thermal diffusivity parameter and Brownian motion are also considered. The useful parameters are followed for re-taking the dimensionless form of equations. The numerical scheme namely bv4c is implemented for computing the algorithmic simulations. The onset of all active involved quantities are investigated. The listed graphical outcomes yield that presence of melting parameter and Weissenberg number improves the nanofluid velocity while reverse trend for velocity profile is observed for curvature parameter. An increasing heat transfer pattern is executed for Biot number and curvature parameter. It is also interesting to observe that concentration profile reduces with Marangoni number and Marangoni ratio parameter.
