Nonsimilar analysis of magnetized Sisko nanofluid flow subjected to heat generation/absorption and viscous dissipation

Abstract

This research explores the nonsimilar magnetohydrodynamic (MHD) boundary-layer (BL) Sisko nanofluid flow over a vertically placed sheet under the impacts of heat generation/absorption and viscous dissipation. The flow is propagated under vertical stretching of the sheet and utilizing natural forces. Flow problem is formulated by employing governing relations and equations are transformed into dimensionless form through the nonsimilar methodology. This dimensionless partial differential system is simulated computationally by using the analytical local nonsimilarity method (LNM) via numerical finite difference based built-in Matlab algorithm bvp4c. Impacts of the effective dimensionless emerging parameters on convective transport analysis are examined. Furthermore, the correlations of drag coefficient, local Nusselt, and Sherwood numbers for significant parameters have been developed. It is noted that the material parameter augments the nanofluid velocity, temperature, and concentration field. The higher the magnetic field drops the fluid velocity however the thermal and concentration profiles increase. The greater estimations of the thermophoresis parameter have a rising impact on the concentration profile, while the higher Lewis number and Prandtl number have an inverse response against the concentration profile. Most of the real-world boundary layer flow problems are nonsimilar, which is an innovative point of this article. So, here we discussed the nonsimilar analysis for the considered problem. According to the author's observations, the declaration of non-similar analysis for the problem under consideration hasn't yet been analyzed in published literature.
