Abstract: This paper used large deformation finite element theory, updated Lagrangian formulation, finite difference method, and incremental theory to develop a three-dimensional thermo-elastic-plastic simulation ...

Abstract: Landslide movement is one of the threats for the structural integrity of buried pipelines that are the main ways to transport oil and gas. In order to offer a theoretical basis for the design, safety evaluation, and ...

Abstract: A numerical simulation method is adopted to analyze the effects of three types of defect geometries ((1) a single defect on the inner surface, (2) a single defect on the outer surface, and (3) double coaxial defects on the ...

Abstract: A numerical investigation was performed to study the thermo-hydraulic performance in an enhanced tube with crossed helical dimples. The simulations were carried out in the Reynolds number range of 5000–30,000 in crossed ...

Abstract: When treating drinking water using UV/H2O2 advanced oxidation, the H2O2 residual is usually quenched to allow for downstream chlorine stability. In some utilities, monochloramine (NH2Cl) is used for secondary disinfection, ...

Abstract: Heat transfer enhancement is an important thermal–hydraulic phenomenon in heat exchangers. Previous investigations mostly focused on unidirectional heat transfer enhancement inside the tube. In order to realize the ...
