论文摘要
流体温度对于分析热液压的热传递很重要。对多相流中流体温度的准确测量或估计具有挑战性。这是由于每个阶段与温度信号混合的热电偶信号和不可忽略的噪声。这项研究提供了一种新的方法,可以使用实验时间序列信号在多相流中估算局部流体温度。热电偶信号被认为是具有马尔可夫特性的序列,并且在新方法中使用了粒子滤波器方法来提取流体温度。本文介绍了新方法的完整描述。
Fluid temperature is important for the analysis of the heat transfers in thermal hydraulics. An accurate measurement or estimation of the fluid temperature in multiphase flows is challenging. This is due to that the thermocouple signal that mixes with temperature signals for each phase and non-negligible noises. This study provides a new approach to estimate the local fluid temperature in multiphase flows using experimental time-series temperature signal. The thermocouple signal is considered to be a sequence with Markov property and the particle filter method is utilized in the new method to extract the fluid temperature. A complete description of the new method is presented in this article.
