“…The MCDMs that will be studied in this analysis, will help to evaluate different options for the shaft tip and also they will be classified with the help of a weighting method such as CRITIC, entropy and simple management to identify the weights that will be added at each evaluation criterion, and for the choice of the optimal material the methods used are the following: EXPROM2 (PROMETHEE II), TOPSIS and VIKOR (Espinoza et al, 2018;Kastillo et al, 2017).…”

In Ecuador some automotive spare parts are not manufactured in the country and must be imported. The reason for this is that some materials cannot be found in the market, which is why this research aims to find an alternative material for the rear axle tip of a car. In order to find this material, first an original part is characterised under the ASTM E415 standard for chemical composition testing, where 0.577-0.603% of C was obtained. The hardness is determined with the ASTM E18 standard obtaining a hardness of 322.77 HB. Tensile strength is found through the ratio of hardness vs. tensile strength, obtaining 115.05 kg / mm². Subsequently, a multi-criteria analysis is carried out with the entropy, simple management and CRITIC methods. The weights of each criterion are measured and with the EXPROM II, TOPSIS and VIKOR method the material is selected, where it was established that the optimal option is the AISI 5115 Steel compared to the original material characterised.

“…However, because to changes in physical and chemical qualities, MW has primarily been used in agriculture, industry, and building. It can, for instance, clean wastewater, encourage plant growth, stop metal surfaces from rusting, and enhance concrete performance [9][10][11][12]. Despite the fact that several of the MFimpacted water qualities have the parameters of specific heat, quantity of evaporation, and megawatt boiling point, which are particularly essential in a variety of applications, including condensed systems, thermal power, and other sectors, are the focus of very few studies that have been recorded.…”

“…Therefore, different temperature schedules are needed in commercial equipment like furnaces and water heaters. CFD is a numerical method that has been used to handle the simultaneous transfer of heat, mass, and momentum (fluid flow) with boundary conditions imposed in a specific computational domain, from the standpoint of fluid engineering [12]. Many food processing procedures, such as chilling, drying, baking, mixing, freezing, heating, pasteurization, and sterilization, need the movement of liquids.…”

The effect of magnetic fields on the water remains a highly controversial topic despite much research focused on this topic in the past decades. However, the improvement of water heating in a magnetic field is less controversial. The mechanism underlying this phenomenon was studied in prior works. In this paper, use solar electric induction to study the heating of water in magnetic fields; one distinction between induction heating and magnetic field heating is that the convection in the water heater is varied due to the different heating locations. Using computational fluid dynamics, it was possible to examine the heat load in the heater during induction heating and magnetic field heating, determine its temperature distribution, and flow rate. The heat flow in magnetic field heating was measured over the heater base at the bottom. In induction heating, the analysis was conducted using the distribution of heat production as determined by electromagnetic field analysis. Simulation shows differences in convective flow in the heater during induction heating and magnetic field heating, particularly in the early stages of heating.

“…Undoubtedly, heat transfer through natural convection stands as one of the paramount domains captivating researchers' attention. This is because it affects several industrial applications, such as the cooling and heating of liquids, 1 cooking or drying processes of food products, 2 and metal melting processes 3 . This phenomenon occurs due to a difference in density due to a temperature difference, which results in fluid movement.…”

The objective of this paper is to investigate fluid‐structure interaction (FSI) within conjugate natural convection. An oscillating fin, featuring a heat source placed at different locations, is examined using the Arbitrary Lagrangian–Eulerian formulation. The Galerkin finite element method is utilized to solve nonlinear dimensionless equations. Verification of grid independence is conducted and the model undergoes validation. Simulation outcomes for three fin positions (left, center, and right) and three heat source locations (bottom, middle, and top) are presented, illustrating streamlines, isotherms, and the average Nusselt number. The governing equations and boundary conditions are addressed using the finite element method. Temperature profiles in four scenarios are analyzed, along with horizontal velocities at different levels (0, D/2, D from the bottom wall). Dimensionless time (10−5 ≤ t ≤ 3), Ra = 106, Kr = 10, E = 1011 are used as parameters. The impact of the heat source position on vibratory motion is evaluated through Nusselt number variation, affecting heat exchange in different cases. The results show that heat transfer is minimal for a source location at the center of the fin (c). These findings also offer insights into FSI applications in economics and industry, guiding practical design considerations. Additionally, coupling the vibratory motion of the heat source with the flexible oscillating fin at the same frequency enhances understanding of the system.
