The heat transfer coefficient of ammonia was measured for three different gap sizes of 1, 2 and 5mm. The result shows that the heat transfer coefficient is increasing with a decreasing in gap size. On the other hand, the present data was compared with conventional correlation by Liu et al. The result of that the correlation indicate underprediction heat transfer coefficient. Therefore, Mortada’s correlation which is made for mini-channels was adopted. The correlation for the case of =1mm is closer to present data than the former one.英語フィールド
