For the reasons of eroding, aged interface and valve, installation quality, natural gas pipes on offshore platform are easy to generate holes and crack, all these factors can cause gas releasing. When they mix with air and the density achieves to a certain degree, ignition and explosion area begin to form. Source of ignition will lead ignition and explosion. In order to reduce serious consequences, it is necessary to study diffusion intensively.
We use FLUENT to show release source’s diffusion...
