A novel spectral relaxation approach for nanofluid flow past a stretching surface in presence of magnetic field and nonlinear radiation

Abstract

The goal of current research is to peruse the influences of magnetic field and nonlinear radiation on stagnation-point flow of nanofluid past a stretching surface. The Joule heating and viscous dissipation properties are considered for analysis in present work. The spectral relaxation numerical approach is implemented to solve the principal equations of the problem. Also, the influences of nanoparticles thermophoretic diffusion and Brownian motion, as well as Prandtl, Eckert, Lewis, and Biot numbers are analyzed and discussed in details. As a main result, it can be concluded that by increasing Prandtl number the temperature profile reduces for different values of radiation parameter. Furthermore, the results show that the nanofluid temperature profile rises with increase of Lewis number. In addition, the findings reveal that increasing the strength of the magnetic field affects the temperature and concentration of nanofluid.
