摘要：

A theoretical model is established that describes the evaporating film flow in a rotating miniature heat pipe with an axial triangular grooved internal surface. The theory of thin liquid film vaporization heat transfer is used to predict the evaporation heat transfer in the micro region. The effects of disjoining pressure, surface tension and centrifugal force on the flow are discussed. Results show that the influence of centrifugal force on the liquid film flow and evaporation heat transfer in the micro region is not significant. The influence of superheat on the apparent contact angle and evaporation heat transfer coefficient in the micro region is shown. (C) 1998 Elsevier Science Ltd. All rights reserved.
