Development of Friction Factor Correlation for Single-phase Flow in Micro-fin Tube Using Logistic Dose Response Curve Fitting Method

Tam et al. 1 conducted simultaneous heat transfer and friction factor experiments for the plain and micro-fin tubes. The results showed that the heat transfer characteristics of the micro-fin tubes were the same as the plain tube. However, the friction factor characteristics of the micro-fin tubes in the transition region were different compared to the plain tube. This type of data cannot be easily correlated by the traditional regression method. Therefore, the logistic dose response curve fitting method is proposed in this study. This particular method has been used in correlating the friction factor data in plain tubes (Joseph and Yang 2). In this study, one set of micro-fin tube friction factor data from Tam et al. 1 was correlated by the logistic dose response curve fitting method. All the fully-developed friction factor data for the entire flow regime can be predicted accurately by a composite logistic dose response function within ±10% deviation. The majority of the data (95%) was predicted with less than ±5% deviation.
