Assessing airborne infection risk through a model of airflow evacuation and recirculation dynamics [PDF]

E3S Web of Conferences
In a ventilated room, the indoor airflows are complicated but can generally be defined by an internal recirculating airflow generated by flooding of ventilation air. This concept categorizes the internal room flow (air and contaminants) as consist of two

Effect of Dissolved CO₂ on the Interaction of Stress and Corrosion for Pipeline Carbon Steels in Simulated Marine Environments

Metals, 2023
Offshore pipelines are subjected to stresses (e.g., from fluid flow, mechanical vibration, and earth movement). These stresses, combined with corrosive environments and in the presence of trace gases (O2, CO2), can increase the pipeline’s corrosion rate ...
