Title: A Model for flow boiling heat transfer in augmented tubes and compact evaporators
Author: Kandlikar, Satish
Abstract: The additive model of the convective and the nucleate boiling components employed in the Kandlikar correlation (1990a) for flow boiling in smooth tubes is extended to augmented tubes and compact evaporators. Two augmentation factors, Ea and E are introduced in the convective boiling and the nucleate boiling terms respectively. The fin efficiency effects in the compact evaporator geometry are included' through a reduction in the nucleate boiling component over the fins due to a lower fin surface temperature. The agreement between the model predictions and the data reported in the literature is within the uncertainty of the experimental measurements.
