In the present work, we explored the magnetohydrodynamic boundary layer flow in the presence of pressure gradient across a flat plate. The effects of the slip velocity conditions, thermal Radiation the addition of hybrid Ferroparticles (i.e., a mixture of two types of magnetic nanoparticles for example, (magnetite (Fe3O4) and cobalt ferrite (CoFe2O4)) in base fluid (H2O ) and Porous wall (suction/ injection) are also considered in this study. Basic partial differential equations are transformed into nonlinear ordinary differential equations using the appropriate similarity transformations. Then, this equation was treated numerically by using the Runge–Kutta–Fehlberg 4th–5th order method with the shooting technique and analytically via an efficient method called the Generalized Decomposition Method. The effects of various physical parameters on the velocity and temperature profiles are shown graphically. It is found that the incorporation of hybrid nanoparticles demonstrates a relatively substantial impact on the behavior of dynamic and thermal field; outperforming both non‐hybrid nanoparticles and regular fluid in terms of speed and temperature enhancement. The slip and permeability parameters significantly alter the flow structure. The positive values of the slip and permeability parameters enhance the flow velocity and reduce the temperature, leading to the desired flow behavior. Conversely, adopting negative values of these parameters reverses the effect. Furthermore, the radiation parameter enhances the temperature distribution. Additionally, the boundary layer separation tends to disappear with the increase in the magnetic parameter. The results obtained clearly show the accuracy of the proposed method and also indicate an excellent agreement between analytical and numerical data.

Researchers can learn more about energy losses, temperature distributions, and general flow characteristics by examining the distribution of Ohmic dissipation in the channels under various circumstances. Thus, in this scientific investigation, it delves into the intricate dynamics of Jeffery‐Hamel flow for second‐grade fluids under the influence of velocity slip, magnetic, and electric fields. A transformative journey is set out using the electro‐hydromagnetic second‐grade fluid theory as the basis. The regulating partial differential equations responsible for this fluid flow phenomenon experience a significant transformation, evolving into ordinary differential equations. Then, two distinct but powerful analytical methods are used to analyze these ordinary differential equations: the widely used Adomian decomposition method and the 4th–5th order Runge‐Kutta Fehlberg method, which is enhanced by the shooting operation. Various factors influencing the skin friction coefficient and the dimensionless velocity (represented as “f”) of the second‐grade fluid are examined. The electric and magnetic fields, the Deborah number, and the elusive velocity slip components are among the many physical variables that are observed. The behavior of the fluid inside the channel is affected by these parameters in the same way that cosmic bodies are affected by gravity. As it delves deeper into the topic of fluid dynamics, and makes some interesting discoveries. The lowest parts of the channel exhibit significantly less backflow; indicating a distinct lack of it. Similar to start alignment, this absence is observed when the Hartmann number rises, decreasing the reverse flow until it vanishes completely. In conclusion, these concepts may prove useful for enhancing designs in a range of engineering settings, including environmental remediation and groundwater management.
