Analysis of the Effects of Failure of a Gas Pipeline Caused by a Mechanical Damage

Natural gas continues to be one of the basic energy sources used as fuel in the power sector, in industries and in households. The potential and attractiveness of this fuel is gaining special significance in the current energy transitions from coal-based power engineering to power generation based o...
