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.
Highlights
In the past two decades, nanofluids got the vast attention of researchers due to their proven efficiency in thermal conductivity
The heat transfer capacity of nanofluids is much higher than that of conventional fluid because the thermal conductivity of a fluid can be optimized by adding nanosized particles; a number of studies have been presented by researchers proving this concept for the nanofluids using different sizes, shapes, and concentrations of nanoparticles with different base liquids, on different geometries [3,4,5,6,7,8,9,10,11,12,13]
Numerical simulation is performed with the above-described method, and results are presented graphically to illustrate the impacts of several nondimensional physical parameters for f ′ðηÞ and θðηÞ
Summary
In the past two decades, nanofluids got the vast attention of researchers due to their proven efficiency in thermal conductivity. A base fluid with suspended nanometer-sized particles with different shapes and sizes is called nanofluids. These nanoparticles can be metallic or nonmetallic or oxidic, for example, Al, Cu, Ag, SiO2, Al2O3, Fe3O4, and ZrO2, and base fluids can be H2O, C2H6O2, and engine oil. The heat transfer capacity of nanofluids is much higher than that of conventional fluid because the thermal conductivity of a fluid can be optimized by adding nanosized particles; a number of studies have been presented by researchers proving this concept for the nanofluids using different sizes, shapes, and concentrations of nanoparticles with different base liquids, on different geometries [3,4,5,6,7,8,9,10,11,12,13]. Some key applications of nanofluids are in the field of nuclear plants, micropolymer films, heat exchangers, electronic devices, space technology, and production of heat pipes
