In addition, the decrease of the annuli gap will yield heat transfer deterioration during flowing in narrow annular channels. 此外,環(huán)縫間隙的減小將導致環(huán)形通道的換熱性能下降。
The thermal storage performances of several kinds of paraffin mixtures and polyalcohols binary systems were studied experimentally by differential scanning calorimeter. 利用差示掃描量熱儀實(shí)驗研究了幾種不同石蠟以及它們的混合物和多元醇二元體系的儲熱性能。
