Magneto-Convective Heat Transfer in Micropolar Nanofluid over a Stretching Sheet with Non-Uniform Heat Source/Sink

The objective of investigation is to study the hydro-magnetic boundary layer micropolar nanofluid steady flow past a stretching sheet with a non-uniform heat suction/sink by taking into account of nanofluids containing Cu– water, TiO2–water, Al2O3–water, and Ag–water. As per the geometry of the flow configuration the conservation laws are transformed into a non-linear model. Using the appropriate analoguestransformations, the resultant equations are employing order approach along with shooting technique to derive closed form solutions for momentum, angular velocity, and temperature fields as well as couple stress, skin friction, local Nusselt number, and then to analyse and physical insight of various flow parameters on these fields. Also the numerical computations are performed and plotted through graphs and tables. It is found that the effect of volume fraction of nanoparticles on the fluid velocity, it decreases due to the absence of surface tension forces and hence, the momentum boundary layer thickness reduced. Furthermore, comparisons with published results are in very good agreement. Nomenclature
