管道停输开挖过程传热数值计算
The Numerical Calculation of Pipeline Heat Transfer during the Periods of Shut Down and Excavation
摘要
Abstract
When buried pipeline was running,there were many factors could cause shutdown phenomenon.This could cause serious economic losses.Oil temperature and soil temperature were the important parameters for pipeline shutdown security.So it was significant to study oil temperature field and soil temperature field for the safe operation of buried pipeline.It was simulated that the excavation area temperature during the shutdown of the pipeline.And the simulation was three-dimensional. Calculation areas contained three parts:soil area,pipeline internal area and the excavation area.These temperature fields were changed after excavation.And the changes of these three areas were simulated.The safety shutdown time was obtained by pipeline internal oil temperature changes.The oil temperature was declined after excavation.The influence of excavation area was obtained by observing the oil temperature.The temperature decline reflected the influence range.The results provided a reference for the safety production.关键词
