A computational study of Brownian and thermophoresis effects on nonlinear radiation in boundary-layer flow of Maxwell nanofluid initiated due to elongating cylinder

Abstract

In this article, attention is paid to investigate the effects of non-linear thermal radiations for Maxwell nanofluid flow, flowing due to elongating cylinder. For better understanding of variations in heat transfer, non-linear heat generation is also considered. The equations of flow, heat and mass transfer due to incorporation of nano particles, are modeled through Navier-stoke, energy and concentration equations. The reduced partial differential equations are transformed into dimensionless ordinary differential equations with the help of appropriate transformations. The reduced system of ordinary differential equations is simulated by means of efficient technique namely shooting method. Significant difference in the heat transfer enhancement can be observed through temperature profiles and table of Nusselt number.From the graphs, finally it is concluded that nonlinear radiation provides better heat transfer rate at the surface of cylinder as compare to the linear or absence of radiation effects.

Maxwell nanofluid heat and mass transfer analysis over a stretching sheet

“…Muhammed et al 14 have studied Buongiorno's mathematical model Maxwell nanomaterial flow saturating a non‐Darcy porous medium over stretching surface and identified that enhancement in the temperature and concentration profiles with intensifying values of Deborah number. Majeed et al 15 perceived the sway of nonlinear thermal radiation on Maxwell nanofluid flow, heat and mass transfer characteristics over elongating cylinder and reported that the effects of nonlinear thermal radiation provides better heat transfer rate at the surface of cylinder compared to problem in the presence of linear thermal radiation. The effects of activation energy and nonlinear thermal radiation on boundary layer Darcy‐Forchheimer flow of Maxwell nanofluid over stretching sheet were discussed by Sajid et al 16 Shen et al 17 introduced the nanoparticle shape to study fractional Maxwell viscoelastic nanofluid.…”
