Consequently, when designing the a pipeline. As a way to solvein the pipe is about 1 mswith pipeline thawing and subsidence, Ushaped air-ventilated pipe, the horizontal section length need to which requires into account composite structure consisting of a U-shaped air-ventilated pipe, be minimized as you can, exactly where an ideal length is about 0.1 plus the underground pipeline supportm. offers cooling and temperature reduction ofWater 2021, 13,12 ofthe permafrost about the pipeline, was proposed in this work. With regards to the CRCOP because the study subject, and applying the wind-speed boundary conditions monitored on web site, theoretical and numerical analyses with the U-shaped air-ventilated pipe were carried out. Primarily based on the outcomes of these analyses, the following conclusions are drawn. (1) In 2014, the seasonal thawing depth near the pipeline in Jagdaqi along the CRCOP reached five.eight m; in 2019, the seasonal melting depth close to the pipeline reached practically 10 m. This represents a C6 Ceramide custom synthesis development rate of about 0.84 m -1 , threatening the protected and stable operation from the pipeline; The U-shaped air-ventilated pipe structure features a good ventilation capacity. Windpressure distinction may be the driving force for the natural ventilation on the U-shaped air-ventilated pipe structure. Because the density differences among the inside and outside in the pipe are tiny, the impact in the thermal pressure difference on the ventilation within the U-shaped air-ventilated pipe is negligible. The impact of neighborhood resistance loss on the ventilation in the pipe is comparable to that of resistance loss along the pipe. This similarity is mainly because of the a lot of bends along the U-shaped air-ventilated pipe. Inside the design with the U-shaped air-ventilated pipe, and thinking of the comfort of installation and actual requirements, the pipe diameter is suggested to be about 0.3 m. Because the horizontal section of your U-shaped vent pipe will cause improved resistance loss along the pipe, resulting in a reduction from the typical wind speed in the pipe, the horizontal section length from the U-shaped vent pipe needs to be decreased as possible, where a perfect length is about 0.1 m.(two)(3)(four)Author Contributions: Conceptualization, Y.C.; methodology, Y.C.; application, Y.C.; validation, Y.C. and G.W.; formal analysis, Y.C.; investigation, Y.C., G.W., D.C., K.G., L.T., H.J. and F.C.; sources, G.L.; data curation, G.L.; writing–original draft preparation, Y.C.; writing–review and editing, Y.C.; visualization, G.W.; supervision, G.L.; project administration, G.L.; funding acquisition, G.L.
