Multi-vent module-based adaptive ventilation to reduce cross-contamination among indoor occupants

TL;DR: In this paper , the authors developed an accurate modeling framework based on computational fluid dynamics (CFD) theory and method for accurate numerical simulation is an important method to increase the understanding of the health effect of face masks and to develop high-performance ones.

TL;DR: The effectiveness of various mechanical and natural ventilation systems in mitigating indoor airborne contaminant spread varies based on specific room contexts and assessment criteria. While MV and DCV exhibit the highest contaminant concentrations and infection risk, stratum ventilation consistently yields the lowest contamination levels. Single-sided ventilation and windcatcher ventilation demonstrate poorer air quality compared to other systems. Specific recommendations are provided for each ventilation method to minimize the transmission of contaminants into occupants' breathing zones.

TL;DR: In this paper , the authors compared three column attachment ventilation models (i.e., circular, square and cross-shaped) by numerical simulation and experimental methods, the latter were mainly employed to verify and optimize the CFD model.

TL;DR: The Middle East respiratory syndrome coronavirus (MERS-CoV) is a lethal zoonotic pathogen that was first identified in humans in Saudi Arabia and Jordan in 2012.

TL;DR: It is argued that existing evidence is sufficiently strong to warrant engineering controls targeting airborne transmission as part of an overall strategy to limit infection risk indoors, and that the use of engineering controls in public buildings would be an additional important measure globally to reduce the likelihood of transmission.

TL;DR: The following scientists reviewed the document: Jonathan Abbatt, John Adgate, Alireza Afshari, KangHo Ahn, Francis Allard, Joseph Allen, Celia Alves, Meinrat O.Hussein, Gabriel Isaacman-VanWertz, Jouni J.C.Johansson, Jan Kaczmarczyk, George Kallos, David Katoshevski, Frank Kelly, Soren Kjaergaard,Luke D.

TL;DR: In this article, a review panel comprising medical and engineering experts in the fields of microbiology, medicine, epidemiology, indoor air quality, building ventilation, etc. systematically assessed 40 original studies through both individual assessment and a 2-day face-to-face consensus meeting.
