smoke

This paper deals with an experiment made in a rest room located in the living quarter of a Norwegian oil platform in the North Sea. The project was to get an area for the non-smokers with no odour of cigarette fumes : a non smoker could then sit next to a smoker when placed upstream the airflow.
It was decided to install a variable air volume (VAV) system regulated via a general air quality sensor.The sensor was located adjacent to the exhaust slot nearest to the non-smoking area.

In this paper measurement of local ventilation index and air exchange efficiency is presented. That work shows that with carefully design solutions, health risks for restaurant workers and bartenders can be considerably reduced. High ventilation efficiencies have been obtained thanks to the separation of non-smoking and smoking areas with air-curtains.

Chinese food is delicious. There are many kinds of cuisine. But the stir-fry, fry and deep-fry produce a large amount of steam and smoke which cause indoor air pollution seriously. So it must be controlled. The paper gets some flow distribution regularity of steam and smoke current in Chinese cooking by testing in laboratory and advances a new method to prevent the diffusion of smoking current-kitchen hood with forced air screen. By comparing with other removers, the equipment can save heat (cold) load and improve indoor air condition greatly.

This paper discusses the numerical study of the effectiveness of atrium smoke exhaust systems. This study is part of a project initiated by A SH RAE and the National Research Council of Canada (NRCC), in which both physical and numerical techniques were employed to determine the effectiveness of such systems and to develop guidelines for their design. This paper presents numerical predictions obtained using a computational fluid dynamics (CFD) model and compares the numerical results with the experimental data obtained from tests performed in this project.

This paper addresses atria smoke management systems where it is intended that occupants will be in contact with smoke. While this approach is unusual, it is recognized by several authoritative publications on atrium smoke management. A tenability analysis for an atrium smoke management system needs to account for the effects of ( 1) exposure to toxic gases, (2) exposure to elevated temperatures, and (3) smoke obscuration. Much of this paper consists of adapting and presenting well-established tenability methods for application to smoke management.
