本文對(duì)圓管、橢圓管和滴形管的管外空氣側(cè)的流動(dòng)進(jìn)行數(shù)值模擬比較三種強(qiáng)化換熱管的換熱性能的優(yōu)劣,得出滴形管的流動(dòng)與傳熱綜合性能較優(yōu),橢圓管次之,圓管較差的結(jié)論,并利用場(chǎng)協(xié)同原理對(duì)模擬結(jié)果進(jìn)行分析,驗(yàn)證了數(shù)值模擬結(jié)果的正確性。根據(jù)換熱性能分析標(biāo)準(zhǔn)定義了無(wú)量綱參數(shù)N0來(lái)綜合評(píng)價(jià)換熱表面的強(qiáng)化換熱效果,得出和場(chǎng)協(xié)同原理相似的結(jié)論。 、 |

| The author gives us a numerical simulation on the air motion outside the tube about circular tube, elliptical tube and dropwise tube, making comparisons on the heat transfer function of three different heat exchangers. Then the author gets the conclusion that the air motion and comprehensive heat transfer function of the dropwise tube are the best, then comes the elliptical tube, and the lest one is circular tube. Then the author making analysis by the field synergy principle and verify the conclusion. According to the heat exchange performance analysis standard, the author defines the dimensionless parameter N0. to evaluate the heat transfer function of heat exchange surface, and reaches a similar conclusion with field synergy principle. |
