Three-Dimensional MHD Rotating flow of Radiative Nanofluid over a Stretched Sheet with Homogeneous-Heterogeneous Chemical Reactions

Carbon nanotubes (CNT) are used in a variety of applications, including energy storage, device modelling, automotive parts, water filters, thin-film electronics, coating etc. The present article investigates the steady three-dimensional (3D) magnetohydrodynamics (MHD) rotating flow of water based nanofluid containing CNT namely SWCNT and MWCNT past a stretching/shrinking sheet in occurrence of magnetic field and homogeneous-heterogeneous chemical reactions. Further, the heat transfer phenomena is analyzed in presence of thermal radiation and heat source/sink. The governing partial differential equations (PDEs) are converted to non-linear ordinary differential equations (ODEs) by using suitable similarity transformations, and then solved numerically using bvp4c code of MATLAB software. The impacts of magnetic field, rotational, suction/injection, thermal radiation, heat source/sink parameters, nanoparticle (NP) volume fraction, and homogeneous and heterogeneous reactions on the velocity, temperature, and concentration profiles as well as the skin friction coefficient and Nusselt number are presented in graphs and tables. It is found that The primary velocity decreases while the second velocity increases for higher values of rotational parameter and the flow dominates in MWCNTs the SWCNTs.
