Problem Description Sorption heat storage systems are attracting growing interest due to their high energy density and loss-free heat storage capability, making them a promising solution for storing surplus solar energy in summer for use in winter in residential buildings. However, these ... En savoir plus

Hunting Lodge St. Hubertus is one of the most prominent Dutch buildings from the early twentieth century. An extensive study of wind and wind-driven rain (WDR) was conducted to provide insight into the moisture load of the building facade, using measurements and CFD simulations. COMSOL ...

The material wood is frequently used in construction industry for several elements such as window frames. However, as a hygrothermal material, wood is sensitive to moisture induced damage. In this context, the moisture uptake of wood based windows logged with an integrated relative ... En savoir plus

A model built with COMSOL Multiphysics® to exploit meteorological forecasts and instant outdoor meteorological data (temperature, solar radiation, moisture, wind speed and direcition, etc.) together with indoor ambient data (air temperature, radiant temperature of enclosures, etc), ...

Phase change materials (PCMs), including shape memory alloys (SMAs), often exhibit thermal hysteresis behavior during phase transitions. Traditional modeling approaches employ binary or threshold-based phase transition models, which is often sufficient for steady-state applications or ... En savoir plus

Laser-induced photovoltage in ferromagnetic thin films is often explained by magneto-thermoelectric effects such as the anomalous Nernst effect (ANE). ANE appears when thermal gradients interact with magnetization. While power loss in flat films can be estimated analytically, numerical ... En savoir plus

This work presents a comprehensive modeling and validation study of MEMS-based infrared (IR) emitter chips using a neural network-assisted inverse modeling approach in COMSOL Multiphysics. Starting from a single baseline chip geometry, a simulation model was developed that captures the ... En savoir plus

The problem of storage, and release of thermal energy is an important challenge in various industrial fields. Several systems for thermal energy storage exist like phase change materials (PCM) and thermochemical storage [1]. The first system usually addresses short term storage (day ... En savoir plus

Pioneering Computational Models for the Built Environment Energy performance is becoming more important in the build environment. With better insulated buildings, the possibility of moisture problems and thermal bridges increases. There for, it is not only important to determine the ... En savoir plus

Temperature measurements of the subsurface are available due to hydrocarbon exploration in the project area, where the average drilling depth is about 2-4 km and the deepest well reaches about 8.5 km. Since the data is heavily uneven distributed, standard interpolation techniques did not ... En savoir plus
