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.

It is well known that solar energy is the main source of thermal energy coming from the sun responsible for huge operations in engineering studies. It can be seen in the technology of photovoltaic cells, solar streetlights, solar energy plates, and solar water pumping. This study is for investigating solar radiation as well as a method to improve the performance of the solar water pump (SWP) with the use of solar radiation along with nanotechnology. The thermal transfer performance of the pump is checked for the case of many impacts including heat radiations and variable thermal conductivity. An Oldroyd‐B nanofluid with entropy production analysis has been scrutinized as a working coolant liquid in the system. Graphene oxide (GO) and Cu nanoparticles have been employed in engine oil (EO) as the base liquid. It is noticed that the heat transfer performance of SWP increases in the case of amplification in thermal radiation and temperature‐dependent thermal conductivity characteristics. In comparison to low thermal conductivity nanofluid, high thermal conductivity nanofluid provides the best capability for heat transmission. The thermal efficiency of the used (GO/EG) nanofluid has been enhanced by between 7.70% and 26.68% than (Cu/EO) nanofluid.

“…The properties of hybrid nano-fluids are highly dependent on the type of nano particles used, their concentration, and the base fluid. Therefore, the optimization of hybrid nano-fluids requires careful selection of nanoparticles and base fluid and a detailed understanding of their interactions [13][14][15][16][17][18][19].…”

In the present work, we explored the magneto hydrodynamic (MHD) flow in the pressure gradient across a flat plate. The effects of the magnetic field and the addition of ternary hybrid nano-fluid (i.e. a mixture of three nano particles for example ( \({Tio}_{2}, {Sio}_{2, } and {Al}_{2}{o}_{3}\)) in mixture base fluid ( \({H}_{2}O-{C}_{2}{H}_{6}{O}_{2}\) ) are also considered in this study. Basic partial differential equations (PDEs) are transformed into nonlinear ordinary differential equations using similarity transformation. Then, this equation was treated numerically by the 4th–5th order of the Runge-Kutta-Fehlberg method with shooting approaches and analytically by a new method called the Daftardar-Jafari Method (DJM). The effect of various physical parameters namely the magnetic field (M), the volumetric fraction of the nanoparticles, the pressure gradient \(\left(m\right)\) on the velocity distribution, the type of the nanoparticles and the coefficient of friction \({\text{C}}_{\text{f}}\), of the theoretical results obtained confirm that the ternary hybrid nano-fluid has a better dynamic property than the hybrid nano-fluid, as well as the efficiency of the adopted DJM technique.
