KKL correlation for simulation of nanofluid flow over a stretching sheet considering magnetic dipole and chemical reaction

Abstract

The enhancement of heat transfer is an important factor in heat exchangers, nuclear reactors, electric coolers and solar collectors. The enhance in rate of heat and mass transfer can be achieved by choosing suitable nanofluid or ferromagnetic fluid as an active liquid. In this connection, we have investigated the ferromagnetic nanofluid flow past a flat elastic sheet with porous medium and chemical reaction. Further, 𝐶𝑢𝑂 − 𝐻 2 𝑂 nanofluid is considered and simulated through the Koo and Kleinstreuer-Li (KKL) nanofluid model. The described governing equations are reduced to ordinary differential equations (ODE's) by means of apt similarity transformations and then they are numerically tackled using Runge Kutta Fehlberg-45 (RKF-45) scheme along with shooting method. The graphical results of the velocity, concentration and thermal profiles along with skin friction, Sherwood and Nusselt numbers are found to get an obvious insight of the existing boundary flow problem. The results reveal that, increasing values of ferromagnetic interaction parameter decays the velocity gradient but converse trend is depicted in thermal gradient due to the frictional heating between fluid layers. The increasing values of porosity parameter slowdowns the rate of heat transfer and velocity gradient.

Heat and Mass Transfer Analysis in Chemically Reacting Flow of Non-Newtonian Liquid with Local Thermal Non-Equilibrium Conditions: A Comparative Study

“…It is very important to choose the appropriate integrator, as this decides the accurateness of the shooting process. The system of Equations ( 10), ( 12), ( 13) and (15) with the boundary constraints (11), (14), and ( 16) have been numerically solved by applying the Runge-Kutta integration scheme together with the shooting iteration procedure. Thus, Equations ( 10)-( 16) are transformed into a system of first-order differential equations.…”

Viscoelastic hybrid nanofluid flow over a vertical plate with sinusoidal surface temperature variations

“…Compared to nanofluids, hybrid nanofluids had decreased skin friction, but increased heat transport rate. In the published literatures [ [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] ] numerous researchers did their work based on nanofluid and hybrid nanofluid considering convective heat transfer and different shapes of geometry.…”

“…Heat and mass transfer are utilized in a wide range of industries, including heating and air conditioning, energy systems, cars, steam-electric power production, disease detection and electronic device cooling 20 – 24 . Ordinary fluid, on the other hand, is unable to meet this requirement of heat transition.…”
