The Study of Gas Leakage Dispersion Rules in the Integrated Utility Tunnel
Abstract
This paper focuses on underground gas pipeline leakage accidents. Through the use of CFD numerical simulation
method for accident ventilation control, this paper has kept the natural gas concentration within a safe range. At the same
time, through ventilation, we studied the control effect of natural gas concentration in the utility tunnel under different air
inlet spacing and different ventilation control. Therefore, by using a reasonable accident ventilation measure based on the
CFD numerical simulation method, we hope to improve the safety performance level of natural gas pipeline operation.
