The book Numerical modeling of high-temperature corrosion processes book updated with results published in papers and reviews in the last twenty years. Literature review suggests that little research has been undertaken on numerical prediction of concrete crack width, especially by considering the corrosion as a nonuniform process.

This paper attempts to develop a numerical model to predict concrete crack width for corrosion-affected concrete structures under realistic nonuniform corrosion of. Numerical Modelling. Numerical modelling is the other main approach where the conservation equations are applied to the finite control volumes and are solved using numerical methods to obtain the relevant thermodynamic properties.

Numerical modeling of the first one is relatively easy and can be a source of data for a deeper understanding of the heat transfer processes, occurring within the boundary layer. From the application point of view, only the jets array is able to transfer high heat fluxes, from real devices.

It also considers the related corrosion phenomena of carburization and nitridation. After an introductory chapter setting out the key processes involved in metal dusting, the book reviews how this corrosion process affects a range of metals such as iron and steel, as well as nickel-based and chromium-based high-temperature alloys.

High Temperature Oxidation and Corrosion of Metals, Second Edition, provides a high level understanding of the fundamental mechanisms of high temperature alloy uses this understanding to develop methods of predicting oxidation rates and the way they change with temperature, gas chemistry, and alloy composition.

An experimental and numerical study of thermal profiles of L stainless steel during selective laser melting (SLM) was developed. This study aims to present a novel approach to determine the significance and contribution of thermal numerical modeling enhancement factors of SLM.
