Abstract

This paper firstly introduces the basic principle of void fraction of gas-liquid two phase flow in evaporative cooling generator in ray test, calculates the penetrate coefficient of multiple X-ray source in evaporative cooling coolant and its test pipes. The experiment studies the decay laws of x-rays and isotope γ-rays in evaporative cooling coolant, tests the void fraction of gas-liquid two phase flow in evaporative cooling, which is compared with the model theory calculation results. From the analysis and the discussion, it is concluded that using isotopic γ-rays shows moderate energy, good monochromaticity, and the test of void fraction of gas-liquid two phase flow in evaporative cooling is more ideal.
