A general criterion for evaporative heat transfer in micro/mini-channels
(2010) In International Journal of Heat and Mass Transfer 53(9). p.1967-1976- Abstract
- This paper presents a general criterion to classify a channel as micro-channel or macro-channel. Experimental results of saturated-flow boiling heat transfer in micro/mini-channels for both multi- and single-channel configurations were obtained from the literature. The collected database contains 4228 data points, covering a wide range of working fluids, operational conditions, and different micro-channel dimensions. Seven existing correlations were evaluated against the database to verify their respective accuracies. A combined non-dimensional number Bo * Rel0.5 = 200 was introduced as the new conventional-to-micro/mini-channel criterion. In addition, a generalized prediction method was proposed based on the new criterion, with accurate... (More)
