Summary: This paper investigates the MHD stagnation-point flow of Cu-Al2O3/H2O hybrid nanofluid on a convectively heated shrinking disk, taking into account suction, Joule heating, and viscous dissipation effects. Numerical solutions reveal the existence of two solutions, with the first solution being physically stable. The results show that an increase in suction and magnetic parameters enhances the heat transfer performance, while the Eckert and Biot numbers have no effect on the critical value. The temperature profile decreases with an increase in the velocity ratio parameter, Eckert and Biot numbers, while the velocity increases with an increase in the velocity ratio and magnetic parameters.

Summary: This analysis reports on the water-based Cu and CoFe2O4 hybrid nano liquid flowing across a permeable curved sheet under the influences of inertial and Lorentz forces.

Summary: This study investigates free convection heat transmission in hybrid nanofluids across an inclined porous plate. It is found that water-based hybrid nanofluid has a higher velocity than sodium alginate-based hybrid nanofluid. The Casson parameter has a dual effect on the momentum profile, and the memory effect reduces with an increase in fractional restriction. The results also indicate that increasing the heat transmission in the solid nanoparticle volume fractions enhances heat transmission.

Summary: In this article, an approach for finding the exact solution of the fractional Fokker-Planck equation is presented. The solution is obtained by transforming the equation and implementing the extended unified method. The results show that the solution is a bi-Gaussian distribution, and the friction coefficient has a significant impact on reducing the standard deviation. Moreover, the influence of the fractional derivative is found to be stronger than that of the fractal derivative, and a mixed-Gaussian solution is obtained.

Summary: In this paper, the authors investigate a terminal value problem for stochastic fractional diffusion equations with Caputo-Fabrizio derivative. The stochastic noise considered here takes value in the Hilbert space W. The main contribution is the study of well-posedness and ill-posedness of the problem under different smoothness conditions of the Hilbert scale space W' (a subspace of W). They find that the problem is well-posed when W' is sufficiently smooth and ill-posed when a certain parameter is smaller, leading to the construction of a regularization result.

Summary: A numerical investigation is conducted in this paper for a class of Riesz space-fractional nonlinear wave equations (MD-RSFN-WEs). The presence of a spatial Laplacian of fractional order, described by fractional Riesz derivatives, is considered in the model. The fractional wave equation governs the mechanical diffusive wave propagation in viscoelastic medium with power-law creep and provides a physical understanding of this equation in the context of dynamic viscoelasticity. A totally spectral collocation approach is used to deal with the independent variables, and the results demonstrate that the spectral scheme is exponentially convergent.

Summary: Studying waste discharge concentration in convergent/divergent channels is crucial for environmental applications. It helps determine the efficacy of treatment techniques and regulatory controls in lowering pollutant levels. This study focuses on the flow and heat transmission characteristics in ternary-based nanofluid systems with divergent and convergent channels. The results show that improving pollutant source variation can enhance concentration in divergent channels while reducing it in convergent channels. Adding nanoparticles increases surface drag force and improves heat management and circulation in nanofluid systems.
