“…The model accomplished the calculation of water chemistry and electrochemistry (corrosion rate) by tak-ing as inputs temperature, carbon dioxide pressure, aqueous solution chemistry, and the flow conditions at the metal surface. Some comprehensive mechanistic models of carbon dioxide corrosion in pipelines were developed successively [12][13][14][15][16][17][18][19]. This kind of model is based on the Nernst-Planck equation, and the focused domain is within the diffusion layer [20].…”

A computational fluid dynamics (CFD)‐based method combined with water chemistry and electrochemical reaction calculation is developed to investigate the effect of fluid flow on carbon dioxide corrosion in an elbow. The mass transfer of reactants and products influenced by flow during corrosion is revealed visually by distribution of main species concentration. The results show that the distributions of main species concentration and corrosion rate on the bare steel surface are in good accordance with the distribution of flow velocity. The maximum corrosion rate appears at the entrance on inner side wall of the elbow, and the corrosion rate decreases along the flow direction. Near the exit of the elbow, the secondary flow arises and enhances the mass transfer as well as the corrosion rate. According to the saturation value, the iron carbonate is more likely to precipitate at the inner side wall near the exit of the elbow. The model is validated by the good agreement between simulation results and published experimental data in prediction of hazardous corrosion region and the regional corrosion rate of the elbow.

“…Its applications are multiple; González-Fernández [9] uses the network method in solving transport problems through membranes, heat transfer and electrochemical systems. In recent years it has been successfully applied in other engineering fields such as elastic waves [19], material resistance [20], corrosion [21], magneto-hydrodynamics [22], flow and transport [4], tribology [23], mechanical problems and chaos [24]. On the other hand, among the future research lines in which the network method can be used we find: seepage [25], real-life case models in hydrologic engineering [26][27][28][29], The set of Equations (6)-(9) has a complex analytical solution (from the point of view of the management for the civil engineer), so it is presumed much more appropriate to solve them by numerical methods.…”

The present work describes the program Simulation of Consolidation with Vertical Drains (SICOMED_2018), a tool for the solution of consolidation processes in heterogeneous soils, with totally or partially penetrating prefabricated vertical drains (PVD) and considering both the effects of the smear zone, generated when introducing the drain into the ground, and the limitation in the discharge capacity of the drain. In order to provide a completely free program, the code Next-Generation Simulation Program with Integrated Circuit Emphasis (Ngspice) has been used as a numerical tool while the Matrix Laboratory (MATLAB) code was used to program and create an interface with the user through interactive screens. In this way, SICOMED_2018 is presented as an easy-to-use and intuitive program, with a simple graphical interface that allows the user to enter all the soil properties and geometry of the problem without having to resort to a complex software package that requires programming. Illustrative applications describe both the versatility of the program and the reliability of its numerical solutions.

Modelling of Alumina Splat Solidification on Preheated Steel Substrate Using the Network Simulation Method

et al. 2020

A mathematical model, consisting of a set of differential equations, for the simulation of the alumina splat solidification on steel substrate is presented. The network simulation method is used to solve the problem, which provides the temperatures and the cooling rate in the splat and substrate with a high temporal and spatial resolution for different values of the preheated substrate temperature. The results of this calculation provide important information for the design of ceramic coatings. The model design is explained in depth and simulated in open source software. As expected, the temperature evolutions in several points of the splat, an important variable to know the type of phases and the effect of the manufacturing parameters on this process, coincide with the experimental results. The model is also checked by another experimental test with tin and a bigger splat, which enables the temperature to be measured during solidification. It is worth highlighting the study of the cooling rate, a fundamental parameter to determine the phase, whether amorphous, gamma or alpha. Furthermore, a sensitive study of the mesh was included in order to optimize the computational time.
