HU Zhuohuan, HUANG Tianke, ZHANG Leyi, et al. Numerical simulation of coupled heat transfer for LNG pipeline[J]. CIESC Journal, 2015, (S2): 206-212.DOI: 10.11949/j.issn.0438-1157.20150712.
Coupled heat transfer was analyzed between liquefied natural gas(LNG)pipeline and environment
which including conduction
convection and radiative heat transfer.Conduction should be focused between pipeline and insulation.Convection and radiative was studied between insulation and environment.Cold exergy loss for LNG pipeline was discussed in addition.Then
numerical stimulation was adopted to analysis the flow and temperature filed around the pipeline.Different insulation materials
Reynolds number
environment temperature and solar radiation was investigated.The results showed the thermal resistance of insulation has a greater effect on the cold loss in LNG pipeline.With the increase of the thermal resistance of the insulation material
the influence of environment temperature
Reynolds number and solar radiation in cold exergy loss decreased.
