Significance of heat generation/absorption in three-dimensional flow of Prandtl nanofluid with convectively heated surface

Abstract

In this article, the hydromagnetic three-dimensional flow of Prandtl nanoliquid subject to convectively heated extendable surface and heat generation/absorption has been discussed. A linear extendable surface makes the flow. Thermophoresis and Brownian motion impacts are explored. Heat transfer via convective procedure is considered. Condition associated with zero nanoparticles mass flux at the surface is used. Prandtl liquid is taken electrically conducted through constant applied magnetic field. Suitable non-dimensional variables lead to strong nonlinear ordinary differential system. The obtained nonlinear differential system is solved through optimal homotopy analysis method. Graphical results have been provided for temperature and concentration fields. Physical quantities like surface drag coefficients and local Nusselt number are sketched and analyzed. Our results depict that the temperature field has a direct relationship with Hartman parameter and Biot number.
