Abstract
Heat transfer and energy storage remain significant challenges for both scientists and manufacturers. Thus far, there has been a focus on the development of innovative heat transfer fluids, including nanofluids. This analysis investigates activation energy impact on heat transfer in magnetized flow of second-grade micropolar nanofluid passing through exponential surface. Further, the influence of heat source and thermal conductivity subjected to swimming microbes are computed. Similarity approximation are used to transform the governing PDEs of viscoelastic model into set of ODEs. Appropriate shooting technique along with Lobatto-IIIa scheme in Matlab is used for numerical computation. The numerical and graphical results against prominent parameters like viscoelastic parameter, Peclet number, velocity ratio parameter, Arrhenius energy parameter, Hartman number, thermal conductivity, thermophoresis parameter, Prandtl number, velocity ratio parameter and Brownian motion on involved profiles are computed. The velocity boundary layer f' is diminished by increasing values of the rotation parameter, magnetic parameter and porosity parameter and boosted for viscoelastic parameter. The thermal profile θ is enhanced by rising approximations of porosity parameter and radiation parameter. The current viscoelastic nanofluid model for heat and mass transfer is being considered to regulate whether it exhibits greater energy storage efficiency compared to conventional nanofluid.
