Numerical investigation on indoor aerosol dispersion due to natural ventilation with single-sided opening [PDF]

open access: yesE3S Web of Conferences, 2023
The purpose of this study is to evaluate the characteristics of ventilation runoff of particles. Using CFD analysis, the indoor space with the single-side opening model is filled with particles and passive scalar to provide differential temperature ...

Controls on boundary layer ventilation: Boundary layer processes and large-scale dynamics [PDF]

open access: yes, 2010
Midlatitude cyclones are important contributors to boundary layer ventilation. However, it is uncertain how efficient such systems are at transporting pollutants out of the boundary layer, and variations between cyclones are unexplained. In this study 15

CFD Investigation of Enhancing Natural Ventilation in Attached Family House Buildings in Hungary [PDF]

open access: yesE3S Web of Conferences, 2023
Energy consumption of the residential sector in Hungary is 12% higher than the EU average. Most of existing house buildings in Hungary are inefficient in term of their indoor comfort and energy consumption. This is where the refurbishment process takes a

Homogeneity of passively ventilated waste tanks [PDF]

open access: yes, 1997
Gases and vapors in the high-level radioactive waste underground storage tanks at the Hanford Site are being characterized to help resolve waste storage safety issues and estimate air emissions. Characterization is accomplished by collecting and analyzing air samples from the headspaces of the tanks.

Pedestrian-Level Urban Wind Flow Enhancement with Wind Catchers

open access: yesAtmosphere, 2017
Dense urban areas restrict air movement, causing airflow in urban street canyons to be much lower than the flow above buildings. Boosting near-ground wind speed can enhance thermal comfort in warm climates by increasing skin convective heat transfer.

Passive cooling of buildings with phase change materials using whole-building energy simulation tools: A review [PDF]

open access: yes, 2017
Buildings contribute to climate change by consuming a considerable amount of energy to provide thermal comfort for occupants. Cooling energy demands are expected to increase substantially in the world. On this basis, technologies and techniques providing
