Analysis of homogeneous–heterogeneous reactions in a micropolar nanofluid past a nonlinear stretching surface: semi-analytical approach

In the present scenario, the application of reactive agents in industries plays a vital role in the production processes of various materials such as paper production, drawing of wires, etc. Keeping in mind it is necessary to discuss the application of heterogeneous and homogeneous chemical reactions in a micropolar nanofluid flow over a stretching surface where the sheet is considered to be nonlinear. In addition to that, the inclusion of heat generation/absorption in the energy equation of an electrically conducting fluid also affects the fluid flow phenomena. In the present analysis, the Maxwell model thermal conductive is considered with Fe3O4, CuO nanoparticles, and water is treated as base fluid. It is very much transparent that the nonlinear dimensional form of the PDEs gets transformed into ODEs and a semi-analytical approach is employed, i.e., Adomian decomposition method (ADM) for those transformed ODEs. The computation for several characterizing parameters is obtained using the mathematical package MAPLE and these are displayed via graphs and tables. An excellent concurrence with the earlier established result is found which validates the result with the current methodology.
