Abstract :
Present model examines the 2-D boundary layer flow of natural convective micropolar nanofluid along a vertically stretching sheet. Moreover, we have considered the simultaneous effects of radiation and convective boundary surface. Influences of nanoparticles are also analyzed for both assisting and opposing flow. Similarity transformations are used to transform the governing nonlinear partial differential equation to ordinary differential equations. The condensed boundary layer equations for nanomicropolar fluid model are solved numerically. The effects of emerging parameters on velocity, temperature, and nanoparticle volumetric expansion profiles are discussed. Stimulating results are presented graphically and explained physically. The heat transfer rate and concentration rate are also displayed graphically for different flow control parameters.
