The impact of Newtonian heating on magnetic Casson nanofluid flow with variable consistency over a variable surface thickness

A boundary layer flow of Casson nanofluid passing through a heated slab due to Newtonian heating with inconstant viscosity streaming over varying surface thickness is investigated. The fluid equations which are non-linear PDE converted ODE by suitable similarity transformation. numerical approach used solve those along several values pertinent parameters such as the velocity power constant m, magnetic parameter H, Ω, Biot number Bi and α, using finite difference method. Detailed impacts these on thoroughly discussed necessary tables graphs plotted for this reason. Comparison previously reported results made sake validation. m observed increase −f ′′(0) value only positive temperature θ(0) decrease −ϕ′(0) except Ω = −3.
