Abstract

This paper scrutinizes the consequences of radiation and heat consumption of MHD convective flow of nanofluid on a heated stretchy plate with injection/suction and convective heating/cooling conditions. The nanofluid encompasses with <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" id="M2"> <a:mi>C</a:mi> <a:mi>u</a:mi> </a:math> and <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" id="M3"> <c:mi>A</c:mi> <c:mi>g</c:mi> </c:math> nanoparticles. We enforce the suited transformation to remodel the governing mathematical models to ODE models. The HAM (homotopy analysis method) idea is applied to derive the series solutions. The divergence of fluid velocity, temperature, skin friction coefficient, local Nusselt number, entropy generation, and Bejan number on disparate governing parameters is exhibited via graphs and tables. It is seen that the fluid velocity in both directions is subsided when elevating the magnetic field and Forchheimer number. Also, the <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" id="M4"> <e:mi>C</e:mi> <e:mi>u</e:mi> </e:math> nanoparticles possess hefty speed compared to <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" id="M5"> <g:mi>A</g:mi> <g:mi>g</g:mi> </g:math> nanoparticles because the density of <i:math xmlns:i="http://www.w3.org/1998/Math/MathML" id="M6"> <i:mi>A</i:mi> <i:mi>g</i:mi> </i:math> nanoparticles is high compared to that of <k:math xmlns:k="http://www.w3.org/1998/Math/MathML" id="M7"> <k:mi>C</k:mi> <k:mi>u</k:mi> </k:math> nanoparticles. The fluid temperature upturns when enlarging the heat generation and radiation parameters. The skin friction coefficients and local Nusselt number are high in <m:math xmlns:m="http://www.w3.org/1998/Math/MathML" id="M8"> <m:mi>A</m:mi> <m:mi>g</m:mi> </m:math> nanoparticles than in <o:math xmlns:o="http://www.w3.org/1998/Math/MathML" id="M9"> <o:mi>C</o:mi> <o:mi>u</o:mi> </o:math> nanoparticles.
