Abstract

Abstract

Experiments have been conducted to study the heat transfer characteristics of single-phase forced circulation when the test tube was under different marine conditions.The experiments measured the wall temperature of test tube to calculate the heat transfer coefficients at different circumferential places.When the test tube was under inclined conditions,the heat transfer coefficient increased at downside and decreased at upside of test tube because of buoyancy effect.When the test tube was under rolling conditions,the heat transfer coefficients fluctuated with the rolling motions,and the Coriolis force dominated the heat trans-fer fluctuation during the rolling motion.CFD method was used to simulate the heat transfer phenomena under marine conditions,and the results were accord to the experimental phenomena.
- Heat transfer coefficient,
- Inclination,
