Reactive Transport Modelling In Active Clays Using COMSOL Multiphysics®

V. Cabrera1, Á. Yustres1, R. López-Vizcaíno1, V. Navarro1
1Geoenvironmental Group, Civil Engineering School, University of Castilla-La Mancha, Avda. Camilo José Cela s/n, 13071 Ciudad Real, Spain

The study of the movement of solutes and their interaction with the solid phase of active clays is a problem of maximum interest in various geoenvironmental engineering applications, but especially in the deep geological disposal of spent nuclear fuel and other highly radioactive ... Read More

Optimizing and Improving the Intensity Flux in a Reflective Type Laser Focusing system

Rufus Patrick1, Ashok Sharma1
1L&T Defence, India

Abstract. A Laser Focusing system (LFS) focuses a single laser beam (single Channel) or multiple laser beams (multi - channel) onto a surface (Specimen). The general motive of a LFS is to focus a train of brief pulses or a continuous beam of light onto a Specimen which heats up its ... Read More

Hybrid 2D/3D fully coupled electrothermal model for three-core submarine armored cables

Juan Carlos del-Pino-López1, PedroCruz-Romero1
1Universidad de Sevilla, Spain

It is a fact that IEC 60287 standard introduces important errors in the computation of the armor losses of submarine three-core lead sheathed armored cables, since the twisting of phases and armor wires is not considered. This results in an overestimation of cable size, and hence its ... Read More

Revisiting Stress Singularity / Concentration Examples with COMSOL Multiphysics®

Ivar KJELBERG1
1CSEM SA, Neuchâtel, Switzerland

Numerical stress singularities (SS) and "true" stress concentration (SC) are regularly encountered in structural analysis and need to be acknowledged with care, such to obtain sustainable models. By following Tony ABBEY's interesting and free Talk-Events over the last months (https:/ ... Read More

Therefore, reducing the rejection level of the heat treated advanced high strength steel (AHSS) strips is an active research area. In this study , the evolution of ... Read More

Modeling of an industrial scale packed bed reactor for steam reforming applications.

A. Biasin1, M. Guiotto1
1CASALE SA, Lugano, Switzerland

In this work, the modeling of an industrial scale, single tube, packed bed reactor for steam reforming (SR) application, typically used to provide hydrogen for ammonia synthesis, is discussed. The tightly coupled mass, energy, and momentum equations used to describe the system have been ... Read More
