Evaluation of influence of an earthquake acceleration upon boiling two phase flow behavior
- 1. Japan Atomic Energy Agency, Tokai, Ibaraki (Japan)
Description
The analysis of boiling two-phase flow in a simulated fuel channel under the condition that earthquake acceleration is imposed on was performed in order to evaluate the influence of earthquake acceleration upon the boiling two-phase flow behavior in fuel bundles of nuclear reactors. From a series of numerical simulations, the following summaries were derived: when the earthquake acceleration is given to the horizontal direction, time change of the predicted void fraction aries a time lag depending on an oscillation period of earthquake and the time lag is maintained; and, the fluctuation characteristic of the predicted void fraction receives strongly the influence of lift force and turbulent force to the oscillation period of earthquake.
