Influence of Different Number of the Open Exhaust Outlets in Tunnel Lateral Exhaust System on Smoke Exhaust Effect

Investigation of the Effect of Exhaust Gas Recirculation (EGR) on pollutants Emission From Si Engine Exhaust Gasese (RESEARCH NOTES)

This paper reports the results of an experimental investigation on the effect of the EGR on the pollutants emission, especially on oxides of nitrogen, from the exhaust gases and performance of the spark ignition engine. Also along with experimental work, a mathematical model for the determination of the effect of EGR on the peak cycle temperature and for the prediction of its effect on the NOx ...

Influence of Alternative Exposure Estimates in the Diesel Exhaust Miners Study: Diesel Exhaust and Lung Cancer.

The landmark Diesel Exhaust in Miners Study (DEMS) studied the relationship between diesel exhaust exposure (DEE) and lung cancer mortality of workers at eight nonmetal mines who were followed from beginning of dieselization of the mines (1947-1967) through December 31, 1997. The original analyses quantified DEE exposures using exposure to respirable elemental carbon (REC) to represent DEE, and...

Experimental investigation on influence of smoke venting velocity and vent height on mechanical smoke exhaust efficiency.

A set of burning experiments were conducted to investigate the influence of smoke vent height and exhausting velocity on mechanical smoke exhausting efficiency. Results have shown that the smoke exhausting process becomes more efficient due to the increased smoke vent height and the decreased exhausting velocity, which eliminate the plug-holing issue with fewer disturbances on the smoke layer i...

Numerical study of the effectiveness of atrium smoke exhaust systems

This paper discusses the numerical study of the effectiveness of atrium smoke exhaust systems. This study is part of a project initiated by ASHRAE 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 obt...
