In this paper we present the development of a mathematical model for the numerical simulation of one-dimensional compressible transient flows in natural gas distribution networks, based on the method of characteristics. This model was developed to validate transient phenomena in distribution networks of piped natural gas, which is why it was decided to build an experimental network with carbon steel pipe, 140 meters in length and two inches in diameter, in order to simulate situations involving localized ruptures. To achieve the safety conditions and calibration of the instruments, the experiments were initially conducted using compressed air, with subsequent use of natural gas. The study included several cases of leakage in the experimental network, which provided evidence that the results obtained show good agreement with the experimental values, thus justifying the use of the model for real cases.
