摘要: Abstract This paper focuses on the heat transfer of gas cooler under optimal discharge pressure. Compared with experimental results, scale CO2 temperature dropping is found smaller in simulation. To make model data more accurate, previous studies emphasized modification coefficient from side, which considerably higher than water side. Through analysis LMTD and principle cask effect, it concluded that has a greater effect CO2. Based Buckingham PI its new dimensionless correlation rise was obtained. When calculating side this correlation, average error ratio exhibited relative decline about 10.26% (for °C). The squared 0.97815 also indicated significant improvement accuracy model. revised can provide reliable basis for design.
