Summary: The primary goal of this article is to control the mixed convective flow and heat transfer of a non-Newtonian Maxwell nanofluid via a vertically slippery stretched sheet through a porous medium using the Soret and Dufour impact. By studying the Buongiorno model, the mass and thermal characteristics of the nanofluid can be determined. The viscosity alteration of the Maxwell nanofluid with temperature is the main focus of the paper. The mathematical model of the problem is built using the principles of conservation of mass, momentum, and energy, and numerically resolved using the shooting method.

Summary: This study examined the impact of Brownian motion and thermophoresis on MHD stagnation-point nanofluid flow towards a vertical stretching surface. The simulation revealed that an increase in Brownian motion leads to an increase in heat transfer rate and a decrease in mass transfer rate, while enhancing thermophoresis effects increases mass transfer rate without dominantly affecting heat transfer rate. The Finite-Difference Crank-Nicolson Method is efficient in handling such nonlinear physical models arising in mechanics.

Summary: This work experimentally studies the laser forming process of cylindrical surfaces. The effects of process parameters such as laser power, laser scanning scheme, and distance between irradiation lines on the radius of curvature of the laser-formed cylindrical surfaces are examined. The design of experiment (DOE) method based on the Box-Behnken algorithm is employed for investigations. Results indicate that increasing laser power decreases the radius of curvature of a laser-formed cylindrical surface. Additionally, the radius of curvature of the cylindrical surface increases with increasing scanning speed, while it decreases with increasing distance between irradiation lines.

Summary: This study conducted an experiment to identify the flow pattern and measure the void fraction of gas-liquid two-phase flow in an upward inclined channel. The experiment was carried out in a 30-meter channel with air and water as the fluid mixture. Three flow patterns were observed in the vertical section: slug, churn, or annular-mist flow. It was found that upstream impacts influenced the interactions and momentum transfer between the two phases, while downstream impacts determined the amount of backward flow caused by the formation of counter-current flow.

Summary: In this paper, the study of fuzzy differential equations (FDEs) in fuzzy calculus is discussed, which provides a proper model to address real problems with uncertainties. Specifically, a class of fuzzy differential equations (FFDEs) with non-integer or variable order (VO) is considered. The main problem is converted to a new problem by utilizing the r-cut representation and is solved using operational matrices (OMs) based on shifted Legendre polynomials (SLPs), leading to a system of nonlinear algebraic equations. The accuracy of the proposed technique is confirmed with an example.

Summary: This paper investigates the thermal flow of an incompressible fluid, specifically focusing on non-Newtonian fluid flows with chemical reactions and heat sources. The study's application is fluid flow around a stretching sheet, which has relevance in polymer extrusion, drawing or plastic films, hot rolling, casting, and other engineering problems. The novelty of this paper lies in using a new and efficient semi-analytical approach, the Akbari-Ganji method (AGM), to solve the governing equations. The finite element method (FEM) is also applied for investigation, and the results show perfect agreement with previous research. Moreover, the results indicate that the Hartmann number and interaction parameters improve velocity profiles, and the fluid velocity decreases with an increase in the Hartmann number.

Summary: The article aims to solve the problem of mixed convection in a porous medium on the half-line by approximating multiple solutions using the quasilinearization method combined with the finite difference method. The nonlinear differential equation is transformed into a sequence of linear differential equations using the quasilinearization approach. The finite difference method is then applied at each iteration to find the approximate solutions. A beneficial scheme is presented to obtain appropriate initial guesses for computing both solutions. The convergence analysis is discussed in detail and numerical results are provided to validate the proposed iterative method.
