Abstract
Abstract Earthquake is one of the most serious phenomena for safety of a nuclear reactor, especially in Japan. The behavior of nuclear reactor may be affected by the fluctuation of gas-liquid two-phase flow caused by the earthquake but not studied enough. In the project, bubbly or plug flow with flow rate fluctuation in a fixed horizontal pipe is studied experimentally. In this paper, the result on the bubbly flow under the flow rate fluctuation is shown. The flow was bubbly flow and/or plug flow in a horizontal circular pipe. The working fluids were water and nitrogen gas. The water was driven by a pump and the flow rate fluctuation was given by a reciprocating piston attached to the main flow loop. he behavior of horizontal gas-liquid two-phase flow under the flow rate fluctuation was measured by image processing and particle image velocimetry (PIV).
