Impact of thermal jump condition on Jeffrey fluid flow consisting nanoparticles: An unsteady case

Abstract

In this study, we exercise the bivariate spectral local linearization method to solve the present problem of an unsteady hydrodynamic flow and heat transfer of Jeffrey nanofluid over a stretched boundary with viscous dissipation effects employing a thermal jump condition at the boundary. The sensitive nature of the problem presented need to split the time domain into small sub-intervals to achieve good convergence and high accuracy of solutions. It is important to note that this problem is heavily influenced by parameter values. An impression in the temperature and concentration field due to thermal and concentration gradient (Soret and Dufour effects) is audited. Coherent evaluation of thermal jump at the bounding surface, magnetic field, Soret and Dufour effects on unsteady Jeffrey nanofluid flow, makes this analysis distinctive. Upshot of present study may be supportive in industrial/ engineering activities in the field of biochemical engineering, meteorology, solar energy transformations, atmospheric research, power engineering, transportation production, polymer manufacturing, sensing micro fabrication, etc. An upturn in thermal slip parameter signifies lesser amount of heat flow from boundary to nanofluid. Dufour number induces an elevating nature in the fluid velocity and nanoparticle concentration whereas Soret number exhibits reverse phenomena.
