This paper studies the character of smoke by fire model test in tunnel,emphasizes on the law of smoke distribution t analyses the length,velocity and thickness of refluxed zone.

By comparing the results,the paper selectively analyzes the influence of different settings of wall boundary conditions on parameters such as smoke temperature and state.

An experimental study of smoke flow in tunnel fire;

For the research interest,the paper has studied the influence of such factors on the smoke movement,as the height of spandrel,the width of horizontal projection,the width of heat passage,the breaking of external wall,as well as the wind speed,etc.

Experimental and numerical studies on smoke movement and control in subway stations are presented.

Analysis is made for smoke movement in large space buildings, and some fullscaletests for comparison are made in USTC and PolyU Test Hall.

Effect of alterative puffing regime on Benzo[a]pyrene delivery in mainstream smoke;

Study on the analysis of benzo[a]pyrene in mainstream smoke;

Research on particle size distribution in cigarette mainstream smoke aerosols

This paper has introduced a kind of new 5 finger rolling plate(5FRP) obstruction detector,its working principle is using photoelectric sensor to survey the rear 5FRP cigarette flow condition,to know whether 5F RP have been blocked.
