Abstract
The goal of this investigation is to explore the influence of viscous dissipation and Brownian motion on Jeffrey nanofluid flow over an unsteady moving surface with thermophoresis and mixed convection. Zero mass flux is also addressed at the surface such that the nanoparticles fraction of maintains itself on huge obstruction. An aiding transformation is adopted to renovate the governing equations into a set of partial differential equations which is solved using a new fourth-order finite difference continuation method and various graphical outcomes are discussed in detail with several employed parameters. The spectacular influence of pertinent constraints on velocity and thermal curves are inspected through various plots. Computational data for the heat transfer rate and skin-friction coefficient are also reported graphically. Graphical outcomes indicate that an augmentation in buoyance ratio and thermophoretic parameter leads to diminish the velocity curves and increase the temperature curves. Furthermore, it is inspected that escalating Deborah number exhibits increasing in the skin friction and salient decreasing heat transmission. Increasing magnetic strength leads to a reduction in the skin friction and enhancement in the Nusselt number, whilst a reverse reaction is manifested with mixed convection aspects.

The effectiveness of Brownian motion and viscous dissipation on magneto-mixed convection flow of Jeffrey nanofluid through an unsteady moving surface is examined with thermophoresis
An aiding transformation is adopted to renovate the governing equations into a set of partial differential equations (PDE) which are sensitive to the initial conditions due to the singularity associated with the highest derivative-term and so the numerical solution is gotten with the aid of a new Fourth-Order Finite Difference Continuation Method (FFDCM) and various graphical outcomes are discussed in detail with several employed parameters
Summary
The novel investigations of nanofluid flow through stretchable surfaces have got valuable attention among study scientists and community because of its abundant practical utilization, in several areas of science and biotechnology. The typical base fluids, e.g., water, alcohol, ethylene glycol, and oil have a weak capacity to promote the heat transfer rate. This complex scenario was resolved by asserting the tiny sized solid fragments in the base fluids. It was basically proposed by Choi [1] that the tendency of the base fluids to embellish the thermal properties can be more effective by adding nanoparticles in these fluids. Nanofluids are spawned by dispersion of nanoparticles along with base fluids and these fluids are the amalgamations of suspended nano-sized pieces (1–100 nm) in base fluids. The constituents of nanoparticles may contain metals, carbides, nitrides, and oxides
