Numerical Study of the Flow of Two Radiative Nanofluids with Marangoni Convection Embedded in Porous Medium

Abstract

The aim of this study is to investigate the flow of two distinct nanofluids over a stretching surface in a porous medium with Marangoni convection. This investigation is studied under the effect of thermal radiation. Here, we have considered Fe 3 O 4 and ZrO 2 nanosized particles suspended in engine oil (EO) base fluid. For the numerical simulation of the flow, the fourth-order Runge-Kutta method and suitable similarity solutions were used. Numerical solutions with graphical representation are presented. Fe 3 O 4 / EO nanofluid is more significant in the cooling process in comparison to ZrO 2 / EO nanofluid. With increased radiation and temperature ratio parameters, a decrement in the temperature field has been noticed for both nanofluids. For increased values of volume friction parameter, a decrement is noticed for velocity profile and increment is noted for temperature profiles for both nanofluids. Also, a reduced velocity profile can be obtained with increased porosity parameter.

“…Tables 4 and 5 show the comparison of our analytical solutions (18) and (24), with the semianalytical solutions obtained by different numerical inverse Laplace transform algorithms (Stehfest's [23], Tzou's [24], Fourier series [25], Talbot [26], and Honig and Hirdes [27]). From these figures and tables, it can be seen that all the numerical inverse…”

“…Modern thermal protection devices, chemical distilleries, building ventilation systems, solar panels, heat exchangers, and electric circuits all contain them [16,17]. Gupta et al [18] used Marangoni convection to study the flow of two separate nanofluids over a stretched surface in a porous medium. Gohar et al [19] investigated a Darcy-Forchheimer flow of Casson hybrid nanofluid via a curved surface that was constantly growing.…”

“…Gangadhar et al [9] discussed nonlinear radiation case for Casson-Maxwell nanofluid flow along with chemical reactions. Gupta et al [10] numerically investigate the radiative nanofluids with Marangoni convection. Kumar et al [11] investigated the slip effects on nanofluid flow with melting phenomena.…”
