Summary: This study investigates the dynamics of bioconvective MHD hybrid nanofluid flow over an exponentially stretching permeable surface, considering thermal radiation, heat generation, chemical reaction, porosity, and dissipative effects. The results show that an increase in the porosity parameter leads to an increase in temperature and a decrease in velocity. The temperature profile is proportional to the radiation parameter, magnetic field parameter, Eckert number, and volume fraction of TiO2 and Ag nanoparticles. The mass transfer rate and motile density number increase with higher values of the chemical reaction parameter.

Summary: In this paper, the impacts of multi-slip with multi-stratification on nanoparticles MHD Carreau fluid flow through a time-dependent stretching sheet with thermal radiation are examined. The solution is obtained using the Keller-box scheme and an implicit finite-difference scheme. The influence of thermal stratification and concentration stratification is also measured. Various parameters affecting the fluid flow are illustrated in diagrams and the numerical findings are well-argued. The results reveal that increasing heavier species, fluid index, and the reaction rate parameter with Prandtl number Pr=5.0, 10.0 and 15.0 will decrease the concentration of fluid within its boundary limits. The behavior of the Weisenberg number on fluid velocity is also studied, showing that fluid velocity declines as the unsteady parameter rises, while temperature and concentration significantly decrease. Higher values of solutal and thermal stratification parameters result in a decay of velocity and thermal boundary layer thickness, while the fluid temperature reflects the opposite behavior.

Summary: The Lie symmetry method is used to obtain exact homotopic solutions for a non-linear double-diffusion problem. Lie point symmetries and corresponding transformations are derived for equations representing heat and mass transfer in a thin liquid film over an unsteady stretching surface, using MAPLE. New (Lie) similarity transformations, different from commonly used ones, are constructed based on these symmetries. These transformations map the partial differential equations of the mathematical model to ordinary differential equations with boundary conditions, leading to new solutions for the flow problem.

Summary: This study examines the nanofluid flow with heat transfer on a stretching sheet using the Cattaneo-Christov heat flux. The influences of thermal and solutal buoyancy, activation energy, thermal radiation, and microorganism concentration are considered.

Summary: In this study, the effect of additional factors such as heat source, magnetic field and Arrhenius activation energy on hybrid nanofluid flow is investigated. The hybrid nanoliquid is synthesized by dispersing silicon dioxide and molybdenum disulfide nanoparticles in ethylene glycol. The flow scenario is analyzed through a system of nonlinear partial differential equations, which are simplified to nonlinear ordinary differential equations through appropriate similarity replacement. Numerical techniques are used to solve the reduced equations. The influence of physical flow parameters on energy, mass and velocity profiles is shown through figures. It is observed that the radial velocity profile increases with the suction factor and decreases with the surface stretching and rotation factor. The heat transmission rate increases with the Reynolds number.

Summary: The dynamics of chemotaxis mechanism for bioconvection in the swirling movement of a flexible heated cylinder with a combination of constant rotation and axial stretching is investigated. The study considers a non-linear viscoelastic fluid with time relaxation and the presence of gyrotactic micro-species. The impact of thermal and concentration gradients on solutal and thermal transportation is analyzed using the Soret-Dufour theory, and an external magnetic field is applied as a constraint. The non-linear differential equations that govern the problem are solved using the bvp5c function, and the results are presented graphically and explained in terms of practical implementation. Each result demonstrates the influence of dimensionless parameters on flow, energy, and bioconvection phenomena, showing that fluid temperature increases due to the preventing solutal deposition and coolant effect caused by Soret and Dufour effects.

Summary: This research investigates the analysis of arterial blood flow through different stenotic regions. Four types of stenotic regions, including triangular, trapezoidal, overlapping (w-shape), and composite formations, are studied for the first time in numerical analysis. An elliptical cross-sectional artery is modeled using a cartesian coordinate system, and the governing partial differential equations are numerically solved with the Open-FOAM CFD software. The results show a high flow profile with minor disruptions near the origin of stenotic sections, and high pressure values near the sharp corners of stenotic regions. Expected irregularities in the flow profile are observed, typical of real-life stenosed artery blood flow problems.

Summary: This article introduces the extension of multigranulation rough set theory to handle uncertainty. A novel optimistic multigranulation roughness of a fuzzy set is proposed based on soft binary relations over dual universes. Two types of approximations of a fuzzy set with respect to forsets and aftersets are established. The algebraic properties of the newly multigranulation rough set model are explored, and both roughness and accuracy measurements are defined. A decision-making algorithm and an example from various applications are provided to demonstrate the suggested model.
