Abstract
Here the performance of double stratification in nonlinear radiative flow of Oldroyd-B nanofluid in stagnation region have been studied. Additionally, the heat sink/source and magnetic influence are enumerated. The Brownian diffusion and thermophoretic impact are also reported. The homotopic algorithm has been worked out for the solution of non-linear ODEs. The Influences of diverse influential parameters on velocity, temperature and concentration are reported graphically. The radiation and thermophoretic parameters are intensifying functions of temperature field. The thermal and mass stratification parameters falloff the temperature and concentration fields, respectively. Additionally, the assessment of numerical upshots with former prose is presented.
