ABSTRACT
The safe design of installations incorporating high pressure pipework and gas handling plant requires the engineering of adequate relief systems. Venting and flaring of natural gas is commonly practiced in order to achieve pressure relief from high pressure handling plant or pipework. The safety of the operation is of utmost importance . The mechanism of gas dispersion into the atmosphere during gas venting is highly dependent on the way in which the gas is released at source. Depending on the initial velocity of the release, the dispersion processes are principally governed by the momentum and density together with the prevailing atmospheric conditions. Hence, there is interest in the effect of j et source structure on the subsequent plume dispersion in the far field.
