Radiative heat transfer due to solar radiation in MHD Sisko nanofluid flow

Abstract

In the present work, the mathematical model for the solar thermal collectors is considered in the form of a nonlinearly stretching sheet. The radiative heat transfer due to solar radiation in magnetohydrodynamic Sisko nanofluid flow over a stretching sheet in the presence of variable thermal conductivity and a heat source is analyzed effectively. The Sisko fluid has been used as a working fluid in the solar collector. The governing boundary value problem is transformed into a system of nonlinear ordinary differential equations using the similarity transformation technique, which is then solved numerically using the finite difference method combined with the quasilinearization technique. The results shown graphically are discussed for the effects of the thermal conductivity parameter, radiation parameter, and heat source parameter on the flow regime. It is observed that increasing values of radiation parameters imply greater thermal conduction and less thermal radiation, as a result of which the nanofluid temperature in the fluid regime will decrease.

Heat transfer analysis in a horizontal anisotropic porous channel with Bi-viscous Bingham nanofluid and temperature-dependent Brownian diffusion

“…As of late, Sanjalee et al (2023b) analytically investigated the heat transfer rate of Bi-viscous Bingham nanofluid suspension saturated in anisotropic porous enclosures of different heights. Some other pioneering works available in the literature are (Basavarajappa et al, 2022;Bisht and Sharma, 2021;Bisht and Bisht, 2022;Sanjalee et al, 2023a;Keerthana et al, 2023) and several references therein. From the thorough review of the literature, it is evident that there is a MMMS 20,4 notable gap in research concerning the analysis of heat and mass transfer properties in Biviscous Bingham nanofluid suspensions within horizontal anisotropic porous channels.…”
