Ainly driven by wind stress. Adhave a adverse pressure; thus, as a result, forced convection is primarily driven by wind stress. Also, a section of horizontalstraight pipe was placed on each the air inlet plus the ditionally, a section of horizontal straight pipe was placed the air inlet and also the outlet of U-shaped ventilated pipe for wind collection. outlet of U-shaped ventilated pipe for wind collection. The two structures talked about above carry out collaboratively for thaw-settlement preThe two structures mentioned above carry out collaboratively for thaw-settlement vention. To meetmeet distinct web-site needs, as unique wind speedsspeeds and geoprevention. To diverse site specifications, such like distinctive wind and geological circumstances, the structures may be combined with insulation layers to achieveachieve a logical conditions, the structures could possibly be combined with insulation layers to a superior coolingcoolingAn automatic temperature-control shutter shutter (ATCS) created of a phasebetter impact. impact. An automatic temperature-control (ATCS) created of a phase-change alloy was added to the mouth from the U-shaped ventilated pipe, as pipe, asin Figure six. The transform alloy was added to the mouth with the U-shaped ventilated shown shown in Figure ATCS closes when the temperature exceeds 0 C to ensure that hot air can not enterenter 6. The ATCS closes when the temperature exceeds 0 to make sure that hot air cannot the U-shaped ventilated pipe,pipe, thereby defending the permafrost about the pipelinetherthe U-shaped ventilated thereby defending the permafrost around the pipeline from from mal erosion.
