Thermo-mechanical model of steel shell behavior in continuous slab casting
… slabs. In order to understand the thermal and mechanical behavior of the shell, a two-dimensional transient stepwise-coupled finite-element model has been developed. The model simulates a transverse section of the slab as it moves down through the mold and below and incorporates the effects of …

Efficient Thermo-Mechanical Model for Solidification Processes and Its Applications in Steel Continuous Casting
The model is then improved to add coupling of heat flow and stress generation that are increment-wise coupled through the size of the interfacial gap. Coupled results are first verified with a solidifying slice, and then quantitatively against the CON2D 2D model of billet casting by fully employing …

An Investigation of Phase Change Material (PCM)-Based Ocean Thermal Energy Harvesting
… from the temperature gradient in the ocean thermocline. Its basic idea is to utilize the temperature variation along the ocean water depth to cyclically freeze and melt a specific kind of PCM. The volume expansion, which happens in the melting process, is used to do useful work (e.g., drive …

The role of frictional heating in the development of catastrophic landslides
In this work, a new thermo-mechanical model is developed by improving on an existing one, applicable to large deep seated landslides and rockslides consisting of a coherent mass sliding on a thin clayey layer. The considered time window is that of catastrophic acceleration, starting at incipient …

Safety of light water reactor fuel with silicon carbide cladding
… with an integrated approach of experiments, modeling, and simulation. High temperature (1100°C~1500°C) steam oxidation experiments demonstrated that the oxidation of monolithic SiC is about three orders of magnitude slower than that of zirconium alloys, and with a weaker impact on mechanical …

Thermo-Mechanical Behavior During Steel Continuous Casting in Funnel Molds
Computational models have been developed to investigate the thermal and mechanical behavior of the solidifying steel shell in continuous casting funnel molds, with the goal of understanding the effect of funnel shape on the solidifying steel shell. The numerical models have been calibrated with …
