Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Accident of asphyxiation and explosion is likely to be induced by the instantaneous leakage of natural gas (NG) highly containing carbon dioxide. It is necessary to study the distribution of emergency region so as to make good emergency response. Distribution of emergency region was simulated using method of computational fluid dynamics. Research suggested that NG highly containing carbon dioxide is of the typical characteristics of dense gas dispersion and the main emergency response region is located in the downwind near-source region. The geometric shape of flammable region caused by instantaneous puff dispersion of NG highly containing carbon dioxide takes on an irregular cirque and the lateral scale varies relatively little, however, the along-wind dimension of the flammable region changes much. Overall the dimension of the flammable region changes over time taking on a parabolic shape whose opening is down until the flammable region no longer exists. The scope of the flammable region caused by instantaneous puff dispersion of NG highly containing carbon dioxide is much smaller both in time and space scales than that of asphyxia region.
