Analytical Approach of Fe3O4-Ethylene Glycol Radiative Magnetohydrodynamic Nanofluid on Entropy Generation in a Shrinking Wall with Porous Medium

Abstract

This research mainly focuses on the effects of heat absorption/generation and radiation on the hydromagnetic flow of Fe3O4-ethylene glycol nanofluid through a shrinking wall with porous medium and the computation of the entropy generation. We considered basic governing ordinary differential equations into partial differential equations by using appropriate similarity solutions. Moreover, hyper geometric function is employing to determine the formulated problem. We analyze the effects of appropriate physical parameters on the Bejan number, Entropy generation, Nussult number, skin friction, fluid temperature and velocity profiles. In addition, the derived result of the present study is compared with those in the existing literature. We noted that the presence of heat absorption and suction parameters reduces the Bejan number and increases the entropy generation, and the heat source, porous medium, radiation parameters minimize the entropy production. The presence of porosity parameter reduced the fluid velocity, improved fluid temperature and minimized the entopy production. Nanosolid volume fraction parameter reduced both Nussult number and skin friction coefficient.

“…mixed convection heat transfer from Al2O3-water nanofluid in W-shaped, copper tube cause the rate of heat transfer coefficient improved with Reynolds number for average wall temperatures of 50 and 60ºC. Magneto hydrodynamic nanofluid flow between two parallel analyzed and results showed concentration of nanofluid diminishes when Brownian movement increments whereas it increases with expands of thermophoretic parameter [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].

Thermal Analysis of Fluid Flow with Heat Generation for Different Logarithmic Surfaces

“…Hatami and Ganji [16] discovered that LSM is more practical than other analytical and semi-analytical methods for cracking nonlinear heat transfer problems in many problems. Recently, several researchers have studied this issue and heat transfer [17][18][19][20][21][22][23][24][25]. Abbaszadeh et al [26] have presented the Galerkin method to solve the Navier-Stokes equation in combination with the heat transfer equation.…”
