Computational studies of gas pipeline junction in unusual operating scenario

Małachowski J.

Journal of KONES

2009

Vol. 16, No. 2

299-304

This research has been inspired by security concerns due to the recent increase in the terrorist threat to gas and crude oil transportation around the world, especially in regions that are of significant value for the energy supplies. Computational mechanics methods will be used in this research to apply shock wave analysis for possible damage assessment of the affected pipelines. These methods may be also used for pipelines at power plants, which are usually placed high on the homeland security priority list. The main goal of this research is focused on establishing effective simulation methodology to study the influence of shock waves (caused by explosion) on pipeline infrastructure elements placed on surface to ensure their security. This study is primarily focused on the behaviour of some type of pipeline junction existing in gas pipeline system which can be subjected to the shock wave produced by the detonation ofhighly explosive (HE) materials. Outcomes of this research are important in preventing damage progression of pipelines under the blast loading. This data will also be used to develop improved design guidelines for safer and less vulnerable pipelines.
