Summary: This study investigates the unsteady Casson nanoliquid film flow over a surface moving with velocity U-w = lambda x/ t. The governing momentum equation is simplified using a similarity transformation and solved numerically. The study analyzes both two-dimensional and axisymmetric film flows. The exact solution is obtained for a specific range of the moving surface parameter lambda. The study also considers the streamline patterns for axisymmetric and two-dimensional flows under stretching and shrinking wall conditions. This research is important for understanding the application of Casson nanoliquid film flow in industries such as coating, laboratories, and painting.

Summary: In this study, the possibility of Casson-Williamson nanofluid flow over a magnetic dipole-enabled curved stretching sheet is considered. A non-Darcy-Forchheimer model with nonlinear thermal radiation, homo-heterogenic reactions, Joule heating, exponential heat propagation, suction/injection, and melting heat peripheral conditions is used. The complex partial differential equations are transformed into more manageable ordinary differential equations using similarity catalysts. The research demonstrates the effects of different parameters on velocity distribution and thermal profile, and presents the flow and temperature distribution using streamlines and isotherms.

Summary: This paper discusses the MHD thermal boundary layer flow of Casson liquid over an extending penetrable wedge with ohmic heating and convective boundary condition. Computational solutions for governing equations are achieved using the homotopy analysis method, examining the influence of various parameters on momentum and temperature field. Results show that convective heat transfer enhances momentum and thermal boundary layer thickness with increasing suction, magnifying the heat transfer rate.

Summary: In this study, the MHD Casson fluid flow on a stretching/shrinking surface with mass suction/injection is investigated. The boundary problem is transformed from highly partial differential equations to ordinary differential equations using similarity variables. Analytical explanations are provided for the resulting ordinary differential equations by considering different controlling parameters and corresponding boundary conditions. The outcomes of the investigation, which can be analyzed using graphical form, reveal the behavior of transverse velocity and tangential velocity under different scenarios and parameter values.

Summary: The study focuses on the impact of magnetohydrodynamic Casson fluid flow across a convective surface with cross diffusion, chemical reaction, and non-linear radiative heat. By converting the governing flow equations into non-dimensional form, the research found that an increase in Sorret number leads to a decrease in temperature and an increase in concentration, while the Dufour number has a negative impact. Additionally, an intensification of the non-linear radiative parameter results in a decrement in Nusselt number and an enhancement in Sherwood number.

Summary: The current research focuses on the exploration of dissipation and chemical reactions in MHD radiative Casson nanoliquid thin film flow generated by sheet stretching. The study remodeled nonlinear partial differential equations into a system of ordinary differential equations using similarity variables and obtained computational results using shooting technique. The outcomes indicate that the thickness of the thin film decreases with increasing unsteady, magnetic, and Casson parameters, with a reduction in wall friction coefficient for higher non-Newtonian parameter estimates.

Summary: The present study focuses on the flow of an incompressible nanofluid following non-Newtonian behavior, including the effects of a uniform magnetic field, Ohmic dissipation, and chemical reactions. The governing equations are solved via the Homotopy perturbation method, and the theoretical findings are presented in graphical and tabular forms. The rotational parameters are found to have varying effects on temperature and velocity components, while the effects of other parameters are qualitatively consistent with previous studies. A comparison with previous reports is made to validate the mathematical model.

Summary: This article examines the flow of thin Casson-nanoliquid film over a porous stretching sheet with suction/injection and a transverse magnetic field. Analytical expressions for velocity and temperature fields are obtained using singular perturbation technique, and the non-linear film evolution equations are solved using a fourth-order Runge-Kutta method. The thickness of the liquid film is found to increase with nanoparticle volume fraction, Casson parameter, Hartmann number, and porosity parameter, with different effects observed for suction and injection.

Summary: This study numerically simulates the time-based unsteady flow of Casson-Williamson nanofluid over a magnetic dipole enabled curved stretching sheet, considering factors such as thermal radiation, Joule heating, an exponential heat source, homo-heterogenic reactions, slip, and melting heat peripheral conditions. The analysis shows that the thermal buoyancy component enhances the velocity regime, while the melting parameter and radiation parameter have counterintuitive effects on the thermal profile. The ferrohydrodynamic interaction parameter slows down the velocity distribution of the nanofluid flow. Graphical representations of streamlines and isotherms are provided to demonstrate the flow and heat distribution.

Summary: This article investigates the radiated stagnation point flow of a time dependent Casson fluid across a permeable stretching/shrinking surface with mass suction, magnetic field and non-uniform heat source and sink. The nonlinear PDEs are transformed into non-dimensionless ODEs and solved using the bvp4c built-in function in MATLAB. The results include temperature, skin friction, velocity and Nusselt number, and show that the friction increases with Casson parameter, suction and Hartmann number. Furthermore, the heat transfer rate decreases with Eckert number and radiation parameter, but increases with surface shrinking and suction rate.
