“…The MATLAB application is used to tackle nonlinear coupled boundary problems using various numerical techniques. In comparison with previous numerical techniques, shooting technique is more accurate and has a tolerance 51 . Since bvp4c is available in widely used numerical computing tools such as MATLAB, and since it is resilient, accurate, efficient, and adaptable, it is a preferable solution for boundary value issues for ODEs.…”

The use of renewable energy sources is leading the charge to solve the world’s energy problems, and non-Newtonian nanofluid dynamics play a significant role in applications such as expanding solar sheets, which are examined in this paper, along with the impacts of activation energy and solar radiation. We solve physical flow issues using partial differential equations and models like Casson, Williamson, and Prandtl. To get numerical solutions, we first apply a transformation to make these equations ordinary differential equations, and then we use the MATLAB-integrated bvp4c methodology. Through the examination of dimensionless velocity, concentration, and temperature functions under varied parameters, our work explores the physical properties of nanofluids. In addition to numerical and tabular studies of the skin friction coefficient, Sherwood number, and local Nusselt number, important components of the flow field are graphically shown and analyzed. Consistent with previous research, this work adds important new information to the continuing conversation in this area. Through the examination of dimensionless velocity, concentration, and temperature functions under varied parameters, our work explores the physical properties of nanofluids. Comparing the Casson nanofluid to the Williamson and Prandtl nanofluids, it is found that the former has a lower velocity. Compared to Casson and Williamson nanofluid, Prandtl nanofluid advanced in heat flux more quickly. The transfer of heat rates are $$25.87\%$$ 25.87 % , $$33.61\%$$ 33.61 % and $$40.52\%$$ 40.52 % at $$Rd =0.5, Rd=1.0$$ R d = 0.5 , R d = 1.0 , and $$Rd=1.5$$ R d = 1.5 , respectively. The heat transfer rate is increased by $$6.91\%$$ 6.91 % as the value of Rd rises from 1.0 to 1.5. This study is further strengthened by a comparative analysis with previous research, which is complemented by an extensive table of comparisons for a full evaluation.

Nanofluids are implementable in a variety of applications, such as heat exchangers, the healthcare sector, the cooling of various devices, hybrid-powered machines, microelectronics, power plants, chemical processes, astronomical technology, cancer treatment, etc. Nanofluids also have enhanced heat transmission and thermal efficiency. The heat radiation of nanoparticles and the natural-convective flow of electrically conducting nanofluids over the rotating disk using Darcy Forchheimer’s porous media, thermal radiation is investigated in this paper. The nanoparticles titanium dioxide and single-walled carbon nanotubes are taken into account with base fluid water. The main goal of this investigation is to enhance heat transfer in nanofluids. The mathematical solution for the model has been obtained through the utilization of cylindrical coordinates. The flow model, which forms the basis of the investigation, is constructed around partial differential equations (PDEs). To address the inherent nonlinearity of these PDEs, physical similarities are employed to transform them into ordinary differential equations (ODEs). Subsequently, the fourth-order Runge–Kutta technique is employed via Matlab to solve these ODEs. The graphical examination of the velocities and temperature with various parameters is an exquisite display of scientific artistry. The magnetic field component is anticipated to exhibit an inverse correlation with velocities, while the temperature profile is expected to surge with the rise of the nonlinear mixed convection parameter. Additionally, the skin friction and Nusselt number are meticulously computed and presented in a tabular format, adding a touch of elegance to the already breathtaking analysis. By boosting the radiation parameter, the Nusselt value declined. Moreover, it is observed that the nanofluids having a laminar nanoparticle shape have a greater heat transfer rate.

The field of fluid dynamics has expanded to study of biological fluids in a magnetic field, a new area known as biomagnetic fluid dynamics. The most notable biomagnetic fluid is blood. The growing interest in problems related to biomagnetic fluid dynamics among researchers is due to its vast applications in biotechnology and biomedical sciences. These applications include magnetic devices for cell separation, blood reduction during surgeries, targeted drug delivery using magnetic nanoparticles to trigger drug release, magnetically induced hyperthermia therapy for most malignant tumors, and magnetic resonance imaging of specific regions of the human body. This study examines the effect of nonlinear radiation on a biomagnetic fluid, specifically blood, flowing through a two‐dimensional, incompressible boundary layer via a stretchable sheet. The flow under consideration is electrically conductive, adhering to the laws of magnetohydrodynamics and ferrohydrodynamics. The governing partial differential equations are transformed into ordinary differential equations using a similarity transformation and solved using the built‐in bvp4c function of MATLAB software. The effects of various physical parameters on velocity and thermal fields are investigated. The influences of the Nusselt number and skin friction are also evaluated against the main parameters. Furthermore, the average Nusselt number is 27.73% at M = 1.1, and when M = 2.5, the value of the average number decreases by 17.73%.
