Effects of Radiative Electro-Magnetohydrodynamics Diminishing Internal Energy of Pressure-Driven Flow of Titanium Dioxide-Water Nanofluid due to Entropy Generation

Abstract

The internal average energy loss caused by entropy generation for steady mixed convective Poiseuille flow of a nanofluid, suspended with titanium dioxide (TiO2) particles in water, and passed through a wavy channel, was investigated. The models of thermal conductivity and viscosity of titanium dioxide of 21 nm size particles with a volume concentration of temperature ranging from 15 °C to 35 °C were utilized. The characteristics of the working fluid were dependent on electro-magnetohydrodynamics (EMHD) and thermal radiation. The governing equations were first modified by taking long wavelength approximations, which were then solved by a homotopy technique, whereas for numerical computation, the software package BVPh 2.0 was utilized. The results for the leading parameters, such as the electric field, the volume fraction of nanoparticles and radiation parameters for three different temperatures scenarios were examined graphically. The minimum energy loss at the center of the wavy channel due to the increase in the electric field parameter was noted. However, a rise in entropy was observed due to the change in the pressure gradient from low to high.

“…13 In a similar study, simulation of H 2 O-based nanofluid flow in a porous medium due to the Lorentz forces was studied by Sheikholeslami and Shehzad. 14 The impacts of slip flow and magnetic field along with a homogeneous-heterogeneous response on MHD Eyring-Powell fluid flow over a rotating disc have been investigated by Gholinia et al 15 Moreover, there are other valuable studies in the above-mentioned fields that are mentioned in References, [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] for additional study.…”

Boundary-domain integral method and homotopy analysis method for systems of nonlinear boundary value problems in environmental engineering

“…Following that, the application of this method was widespread. It was successfully used to solve many linear and nonlinear equations and problems, for example: simulation of nonlinear water waves (Tao, Song, & Chakrabarti, 2007), nonlinear heat transfer (Abbasbandy, 2006;2007;Rashidi et al, 2014;Sajid & Hayat, 2008),differential-difference equation (Wang, Zou, & Zhang, 2007), solving cubic and coupled nonlinear Schr€ odinger equations (Hassan & El-Tawil, 2011) and many others (Akram & Sadaf, 2017;Alamri, Ellahi, Shehzad, & Zeeshan, 2019;Ellahi, 2013;Khan, Bukhari, Marin, & Ellahi, 2019;Kumar & Kumar, 2014;Prakash, Tripathi, Triwari, Sait, & Ellahi, 2019;Riaz, Ellahi, Bhatti, & Marin, 2019;Zeeshan, Shehzad, Abbas, & Ellahi, 2019). These successful applications affirmed the authenticity, flexibility and effectiveness of HAM.…”

A New Computational Technique Design for EMHD Nanofluid Flow Over a Variable Thickness Surface With Variable Liquid Characteristics

“…They managed to show that the shape factor causes stronger convection. Zeeshan et al [36] reported the effect of radiative nanofluid flow under a pressure gradient due to entropy generation and observed an increase in entropy with an increase in the pressure gradient. Ellahi et al [37] investigated flow of a power-law nanofluid with entropy generation and noted that the skin friction coefficient increases at the heated wall.…”
