bosean SF6 room Analysis

Jan 29, 2020In this scenario, SF6 is released at a rate of 0.63 l/min (1.94 × 10 −3 m 3 /s/m 2). This second ventilation strategy aims at creating a flow from the top of the room to the floor. The aim is to quickly direct the gaseous contaminant "rejected" by the patient towards the extraction grilles.

    Although its six fundamental modes have been largely studied up to now, it is not the case for the numerous hot bands that represent the most important part of the SF6 spectrum at room temperature. So, to model correctly the SF6 atmospheric absorption requires the knowledge of the spectroscopic parameters of all states involved in these hot bands.
