Abstract
In order to quantify the damage caused by
undesired events involving leakages of flammable
materials, specific models are used to analyze the
spills or jets of gas and liquid, gas dispersion,
explosions and fires. The main step of this analysis
is to estimate the concentration, in space and time, of
the vapor cloud of hazardous substances released
into the atmosphere; the purpose is to determine the
area where a fire or explosion might occur and the
quantity of flammable material in that area. Recently
with the computational advances, CFD tools are
used to short and medium range gas dispersion
scenarios, especially in scenarios where there is a
complex geometry. However, the accuracy of the
simulating strongly depends on the boundary
conditions. Therefore, this study investigates the
sensitivity degree of the prediction of cloud
dispersion to changes in values of wind speed,
ambient temperature, atmospheric pressure and
ground roughness. This paper con-tributes to an
appropriate assessment of the effects of these
environment conditions to perform an accurate
dispersion simulation using CFD tools and therefore
contributes to a more effective analysis of the consequences.
