Numerical Treatment of MHD Rotating Flow of NanoMicropolar Fluid with Impact of Temperature-Dependent Heat Generation and Variable Porous Matrix

As the micropolar fluid has an essential rule in cervical flows and the polymer industry, this study looks at the developments of Activation energy and temperature-dependent heat generation effects on the MHD boundary layer flow of nano-micropolar fluid over a porous plate. Viscous and Joule heating, exponentially stretching surface, porous matrix with Darcy expression, and linearized Roseland radiation are considered. The differential equations of the applied system are governed theoretically and solved semi-numerically by the shooting method with the aid of 𝑝𝑎𝑐𝑘𝑎𝑔𝑒 (𝑜𝑑𝑒45) . The convenient similarity is used to obtain the system of differential equations. Core results show that activation energy improves the rheological characteristics of the thermal boundary layer by moderating the nanoparticle concentration. Furthermore, the distribution of boundary layer velocity is diminished sluggishly as acts of the porous metrics decline the nanofluid velocity. The novelty of the proposed model is the applications of its components which are related to the heat of the Roseland radiative and transpiration cooling system. The rate of the cooling system has a considerable impact on the properties of the final product in polymer technology with the elongation of plastic sheets, thus presenting the final product with some desired appearances.
