Abstract

Abstract: When buried hot oil pipeline experiences any change, the thermal equilibrium between the oil and the soil around the pipeline is destroyed, and the oil temperature and soil temperature redistribute. In order to study this unstable thermal process, transient temperature field has to be
analyzed. In this paper, mathematical methods (conformal transformation, Laplace transformation etc.) are applied to study unstable heat transmission between the medium in the pipeline and the semi-infinite soil. The formula for calculating soil temperature is derived. In addition, the calculation for shutdown of heated oil pipeline are studied.

Key words: Oil pipeline, Hot oil pipeline, Thermal calculation, Mathematical model
