Curing concrete is best achieved by keeping it nearly saturated at an appropriate temperature until all the cement has fully reacted. However, when installing flooring materials that require low relative humidity (RH) in the concrete, the slab needs to dry as quickly as possible. ... En savoir plus

Large underground mines (LUMs), which constitute over 60% of metal and nonmetal mining operations in the United States, are critical to national infrastructure and materials supply (Bhattacharyya et al., 2023; Gendrue et al., 2021). These mines are characterized by vast entries exceeding ... En savoir plus

In the rapid development cycle of sensor systems, minimizing time-to-market is crucial. However, designing a new MEMS-chip (Micro-Electro-Mechanical Systems) presents significant challenges due to the extensive time required for manufacturing and characterization. This delay affects the ... En savoir plus

Innovative materials, such as ultra-high-performance fiber-reinforced-concrete (UHP-FRC), provide an opportunity to reduce building energy loss by developing energy-efficient facade panels. However, investigating the thermal performance of these façade systems without considering the ... En savoir plus

Toxic and hazardous air pollutants are released during chemical processes. The surrounding area of a chemical facility always has a high risk of air pollution by released chemicals. Furthermore, the personnel of the facility as well as community residents have risks of sudden ... En savoir plus

HETT22 is a software developed through joint efforts by Deflexional and Heidelberg Materials. It enables construction companies to accurately simulate, plan and monitor heat and strength development in concrete after castings. Leveraging the power of the COMSOL Multiphysics® software, ...

Abstract: In order to study thermal conditions and air flows in an office room, 3D FEM simulation model was created. The room is enclosed by walls, floor and ceiling which thermal characteristics are specified by typical heat transfer coefficients and specific heat capacities. Space ... En savoir plus

The pore water pressure in the vadose zone is controlled by the interaction between the soil and the atmosphere through evaporation and infiltration. These processes are strongly influenced by the soil's hydraulic conductivity and water retention properties (Guida et al., 2023). In this ... En savoir plus

In power electronics applications, microelectronic chips face swift temperature changes during operation, characterized by heat pulses of sub-millisecond duration with temperatures rising by hundreds of Kelvin. Over time, these conditions may lead to degradation in the metallization ... En savoir plus

Benchmarks are an important tool to verify computational models. In the research area of building physics, the so-called HAMSTAD (Heat, Air and Moisture Standardization) project is a very well known benchmark for the testing of simulation tools. In this paper we evaluate the use of ... En savoir plus
