Examination of Chemical Reaction on Second-Grade Nanofluid and Micropolar nanofluid due to exponential stretchable sheet: A comparative study
Abstract
• The study focuses on heat transfer in magnetized flow using second-grade micropolar nanofluids, considering the impact of Chemical reaction. • The governing PDEs are transformed into ODEs using similarity approximation, and numerical results are obtained using the shooting technique and Lobatto-IIIa scheme in MATLAB. • Key parameters like viscoelasticity, Peclet number, Hartman number, and thermal conductivity are analyzed for their impact on velocity and thermal profiles. • The study compares the energy storage efficiency of the current viscoelastic nanofluid model with that of conventional nanofluids. 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.
