Abstract
This paper investigates the theoretical description of different shapes of copper nanoparticle in water based fluid. Analytical solution of the governing hydrodynamic equations and graphs plotted. The work showed that heat transfer is rapid due to the presence of radiation. Increase in radiation and chemical reaction also led to a corresponding increase in the temperature and concentration profiles of the nanofluid respectively. For the velocity profile of the nanofluid, only the nanoparticles volume fraction increases the velocity profile of the copper nanofluid. Reynolds number, Grashof’s number and electroconductivity, result to decrease in the velocity profile of the same. The effect of Nusselt number, Sherwood number and skin friction on the nanofluid are also determined.
