Nanoparticle shapes on electric and magnetic force in water, ethylene glycol and engine oil based Cu, Al2O3 and SWCNTs

The lamina shape (m = 16.1576) copper nanoparticles in the presence of Cu-water plays a dominant role on temperature distribution with increase of nanoparticle volume fraction because the electrical conductivity (k = 59.6 Ω− 1m− 1) of copper lamina shape nanoparticles is stronger as correlated with the other mixtures in the flow regime. It is refreshing to notice that the negative value of the temperature profile is predicted in the outer boundary region for M = 0.1 due to the united effects of shape and volume fraction of the nanoparticles in the presence of high density of the water based Cu and Al2O3 nanofluid. It is interesting to note that the thermal boundary layer thickness of the sphere shape SWCNTs - engine oil is stronger as compared to the other mixtures in the flow regime with increase of thermal radiation in the presence of high magnetic field strength M = 100. This is due to the joined effects of thermal conductivity of SWCNTs and engine oil.125
