Mixed convection flow of Cu-water nanofluid having differently shaped nanoparticles past a moving wedge

Abstract

Steady boundary layer mixed convection flow over a wedge moving parallel to a free stream in nanofluid having differently shaped nanoparticles is numerically investigated. The aspire of this article is to examine the combined influences of mixed convection, suction/blowing and variable shape of nanoparticles on motion of nanoliquid past a moving wedge moving faster/slower than the free stream. Nanofluid flow past a moving wedge is commendable of extraordinary concentration owing to its escalating applications in industrialized processes and technologies and so, the significance of this study is that the model is pertinent to a variety of manufacturing sectors for submissive control of nanoelements. The overriding equations under boundary layer approximations along with the matching conditions at the boundary are transformed to ordinary differential equations with the help of similarity alterations. Shooting technique is adapted to solve these equations numerically via Runge Kutta method using MATHEMATICA. Outcomes of the present study for a number of meticulous cases are assessed with the existing outcomes in open text and found a very well conventionality. The effects of various crucial parameters on velocity and temperature profiles of the fluid are accessible and analyzed graphically. The velocity of Cu-water nanofluid increases with the enhanced strengths of suction parameter, wedge angle parameter and also with the enhanced values of nanoparticle volume fraction. In comparison to spherical shaped nanoparticles, elevated temperature is experienced for nanoparticles of non-spherical shape. Also, the skin friction coefficient and surface heat transfer rates for some of the parameters are explored numerically. The outcomes of this learning depict numerous inspiring features that merit supplementary learning of the problem.
