Applications of Nanofluids for the Thermal Enhancement in Radiative and Dissipative Flow over a Wedge

Abstract

The colloidal analysis for H2O and EG (Ethylene Glycol) by considering the influence of radiative heat flux and viscous dissipation is not performed so far. This study is performed to fill up this gap. Therefore, the flow of water and ethylene glycol functionalized magnetite nanoparticles over a moving wedge is examined. For thermal enhancement, two different magnetite nanoparticles, namely CoFe 2 O 4 (Cobalt ferrite) and Mn − ZnFe 2 O 4 ( Mn − Zn ferrite), diluted in the base fluids. Self-similar flow model of a nonlinear nature, containing the volume fraction of nanoparticles is obtained by using compatible similarity variables. For mathematical treatment of the model, the Runge-Kutta scheme is utilized, coupled with shooting techniques. The results for flow characteristics and significant physical parameters are graphically examined. A comprehensive comparative analysis has been made, which proved the reliability of the study.

Numerical Energy Storage Efficiency of MWCNTs-Propylene Glycol by Inducing Thermal Radiations and Combined Convection Effects in the Constitutive Model

“…However, numerical schemes are reliable and efficient for such models. Thus, a numerical scheme along with the coupling of shooting techniques ( Ahmed et al, 2019 ; Khan et al, 2021 ) implemented. Primarily, this technique is based on the reduction of a higher-order nonlinear model into a system of first-order via some sort of transformation.…”

“…Keeping these assumptions in mind, and with the reference from Mallikarjuna et al (2016) and Ahmed et al (2019), the mathematical model are formulated as…”

“…The subscript of f and s refer to the base liquid and MNP, separately. The thermal and physical characteristics for base liquid and MNP are given in Table 2 (Ahmed et al, 2019;Raju & Sandeep, 2017;Gul et al, 2015), where  is the MNP volume fraction and…”

“…Besides, Sulochana et al (2018) also considered magnetite-water and magnetite-methanol as the MNF to be investigated in the moving horizontal needle. Ahmed et al (2019) researched the radiative MNF flow over a wedge for several base liquids and nanoparticles. The stagnation point flow with Newtonian heating of magnetite nanofluid was disclosed by Mohamed et al (2019).…”

Insight into three‐dimensional flow of three different dynamics of nanofluids subject to thermal radiation: The case of water–cobalt ferrite, water–manganese–zinc ferrite, and water–magnetite

“…Using the single‐phase nanofluid model, Jusoh et al 23 observed three types of base fluids: water $$({\Pr }=6.2)$$, kerosene $$({\Pr }=21)$$, and methanol $$({\Pr }=7.38)$$ and they concluded that the ferrofluid with the highest Prandtl number has the maximum heat transfer rate and thermal conductivity. The MNFs flow towards a wedge utilizing cobalt ferrite–water (CoFe 2 O 4 –H 2 O) and manganese–zinc ferrite–water (Mn–ZnFe 2 O 4 –H 2 O) nanofluids was studied by Ahmed et al 27 Hayat et al 28 analyzed the three‐dimensional magnetite nanofluid flow over a nonlinearly stretching sheet with homogeneous–heterogeneous reactions. Mohamed et al 29 studied the impact of Newtonian heating and slip effect on magnetohydrodynamics (MHD) stagnation point flow of a magnetite‐water nanofluid towards a stretching sheet.…”
