Coupled Thermo-Hydro-Mechanical Numerical Modeling of Evolving Fractures in Rocks
(Springer, 2021-04-22)
We present a numerical technique capable of handling evolving fractures in rocks triggered by coupled thermo-hydro-mechanical (THM) phenomena. The approach is formulated in the context of the finite-element method (FEM) ...
Thermo-hydraulic performance modeling of thermal energy systems using parabolic trough solar collectors
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2018-12-26)
Solar energy is one of the most important emerging renewable energy resources. Parabolic trough solar collectors are one of the most used technologies for solar concentrating applications. The main purpose of this research ...
Thermodynamic modeling of a fourth generation disctrict heating system in Brazil
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAPrograma de Pós-Graduação em Engenharia MecanicaUFMG, 2019-02-13)
Heating and cooling is accounted for about half of the global energy use where
domestic heating is the main part of this energy consumption. Due to the importance of
heating in the global energy crisis, district heating ...
Avaliação do comportamento térmico e de segurança de um reator de alta temperatura
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA NUCLEARPrograma de Pós-Graduação em Ciências e Técnicas NuclearesUFMG, 2022-08-12)
Fourth-generation reactors (GEN-IV) operate at much higher temperatures than third-generation reactors and are candidates for the next generation of nuclear reactors, according to the IAEA. Predicting the thermo-hydraulic ...
Thermo-hydraulic optimization of a solar air heater duct with non-periodic rows of rectangular winglet pairs
(2020-09-01)
Surrogate-based optimization is employed to maximize the thermo-hydraulic performance of a solar air heater duct with non-periodic rows of rectangular winglet pairs mounted in the absorber plate. The present optimization ...
Avaliação termo-hidráulica experimental de grades espaçadoras comerciais para reatores PWR e de protótipo fabricado por impressora 3D
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA NUCLEARPrograma de Pós-Graduação em Ciências e Técnicas NuclearesUFMG, 2020-09-04)
Spacer grids are important components in nuclear fuel assemblies of Pressurized Water
Reactors – PWR. These grids are responsible for maintaining the structural integrity
of the fuel assemblies and contribute to enhance ...
