Abstract	Monitoring the surrounding pipeline temperature through fiber optic sensors is an efficient method of detecting leakage of oil and gas. Authors describe a computational model of temperature monitoring in such a leak detection system (LDS). Researchers simulated a longitudinal cross section of an idealized pipe-in-pipe flow-line, where a localized thermal source was placed on the lower boundary of the computational domain. They studied heat transfer rates and temperature profiles of the localized heat source because a detailed understanding of the excess temperature surrounding a pipeline is critical in designing efficient leak detection systems based on the active thermometry method.
