Summary: This work investigates the rheological behavior of magnetized ZnO - SAE 50 nanolubricant over a moving/stationary Riga plate with viscous dissipation and nonlinear heat generation. The novel features of this study include the use of ZnO - SAE 50 nanolubricant as a flow fluid across a Riga plate and the application of the Patel model to enhance the thermal conductivity of the nanolubricant.

Summary: In this study, the influence of the induced magnetic field on the mixed convective electrically conducting fluid flow inside a vertical cylindrical annulus is numerically analyzed. The study finds that as the magnetic Prandtl number (Pm) and Hartmann number (M) increase, the velocity and induced magnetic fields in the annulus decrease due to the presence of the Lorentz force. An increase in the mixed convection parameter enhances the induced magnetic field. Increasing the radiation parameter decreases the fluid temperature and reverses the behavior of the solid temperature. Additionally, increasing values of porous, magnetic, and radiation parameters lead to an unstable system.

Summary: This research investigates MHD mixed convective two-dimensional flow, heat and mass transfer in a concentric inclined annulus. The results show that the concentration and thermal profiles increase in the annular region as the inclination parameter increases. The concentration profile in the annular region also increases with higher reaction rate due to the thickened concentration boundary layer. The external heat generation parameter significantly affects the temperature gradient of the fluid, enhancing the fluid temperature distribution and thermal state. A magnetic field is found to regulate the magnetic convection of the conducting fluid.

Summary: This paper numerically investigates the boundary layer flow of nanolubricant/liquid over a convectively heated rotating disk. The study considers the convection process and the influence of heterogeneous and homogeneous reactions. A comparative analysis is made using two different models with Zinc Oxide (ZnO)-Society of Automotive Engineers 50 nanolubricant and Zinc Oxide-Kerosene. The governing nonlinear equations are transformed into a nonlinear ODE set, and numerical investigations use the Runge-Kutta method. Factors such as flow, temperature, and concentration fields are explored numerically, and the heat transport and shear stress characteristics are evaluated. Results reveal that the ZnO-SAE50 nanolubricant shows enhanced heat transport and the nanolubricant performs better in terms of heat transport rate with increased heat source and porosity parameters.

Summary: This study focuses on the hydromagnetic bioconvective chemically reactive flow of Reiner-Rivlin nanoliquid and analyzes the entropy generation. The thermal relation includes Joule heating, radiation, and dissipation. Soret effect in chemically reactive flow is examined. Nonlinear governing systems are solved using the ND-solve technique after appropriate transformations. Graphical analysis is conducted for velocity, microorganism field, entropy rate, thermal field, and concentration. The graphical descriptions for coefficient of skin friction, microorganism density number, heat transport rate, and concentration gradient are also studied. It is observed that the entropy rate increases with a higher magnetic parameter, while the velocity shows the opposite trend. Increasing temperature enhances thermophoresis and radiation. Radiation intensifies the entropy rate and heat transport rate. Similar effects of drag force and temperature are observed for the magnetic parameter. The concentration and mass transport rate increase with a higher Soret number. Variation in Brownian motion results in concentration decay. A larger Peclet number leads to a decrease in the microorganism field and an increase in the microorganism density number.
