加热棒束通道丝网传感器两相流探测方法及影响因素研究
Study on two-phase flow detection method and influencing factors of wire mesh sensor in heating rod bundle channel
摘要
Abstract
The analysis of gas-liquid two-phase characteristics in heating rod bundle channels is critical for ensuring the safe operation of nuclear reactors.While experimental methods are commonly used to investigate two-phase flow in rod bundle channels,wire mesh sensors are typically applied under room temperature conditions and have seen limited use in electrically heated rod bundle experiments.This study employs the electrostatic field method in finite element simulation software to analyze the influence of electric field in electrically heated rod bundle channels on wire mesh sensor measurements.The simulation results are verified by experiments.Both the simulation and experimental results show that,within a charged rod bundle channel,an increase in the excitation voltage applied to the transmitting electrode enhances the sensor's sensitivity to gas-liquid two-phase flow,thereby improving its detection capability.Imaging experiments conducted under a 20 V excitation voltage confirm the feasibility and effectiveness of wire mesh sensor measurements under such conditions.关键词
