ABSTRACT The quest to efficiently manage heat generation/absorption in industries, such as chemical production, mechanical machines, oil exploration, and aeronautical engineering, is high demand. This study conducted examine the impacts of internal well unsteady mixed convection micropolar fluid through a permeable channel. formulated nonlinear fundamental equations converted from partial differential equation ordinary are numerically analyzed solved using Laguerre Collocation Method along with Gauss–Lobatto points. To verify simulation's accuracy, validation performed via shooting technique fourth‐order Runge–Kutta method acting control aid Mathematica 11.0 software. behavior flow was influenced by various physical parameters, which were plots tables. Impacts skin friction, Sherwood number, Nusselt number evaluated. findings reveal that an improvement term leads enhancement temperature velocity while angular momentum declines. Additionally, it revealed increase nonuniform generation magnetic term, Eckert improves profile, greater Grashof results profile.

The experimental and theoretical analysis of viscous dissipation heat generation/absorption management is crucial in engineering, medical, biological, exploration activities. This study investigates the analytical solution heating thermal gyration magneto-micropolar fluid particles across a resistive medium with internal non-uniform generation/absorption. formulated partial differential equations were appropriately converted into coupled ordinary employing similarity variables along boundary conditions. simulation resultant carried out using collocating weighted residual scheme, result validated shooting technique via Runge-Kutta method order four, Adomian decomposition technique, variational iteration transform method, quasi-linearization as control methods. Tabular graphical representations are provided to illustrate flow characteristics. Taking from results, existence magnetic field retards particle motion. spin gradient vortex viscosity terms reveal reverse occurrence micro-rotation distribution, it seen that porosity term suppresses velocity field. Furthermore, observed parameters enhance generation decrease region. Hence, these findings will assist scientists engineers effectively manage industries where effective transfer activities achieving ideal performance reducing energy waste.
