摘要

摘要: 为了研究二氧化碳爆破射流温度场的演化规律，构建了二氧化碳爆破红外热成像实验系统，开展了二氧化碳爆破实验，分析了二氧化碳爆破射流的空间发展和温度演变过程。研究结果表明：在出现超温现象之前，二氧化碳射流的温度梯度分别为外圈最高、内圈稍低，核心区域温度最低；当出现超温现象时，射流的温度梯度分别为外圈最低、内圈稍高，核心区域温度最高；射流周围的环境温度呈现先降低，后升高的现象。初始泄能压力越高，二氧化碳爆破射流的温度峰值越高，最高温度达到了133.7 ℃，到达温度峰值所需的时间越长；初始泄能压力越低，温度谷值越低，最低温度为−3.4 ℃，到达温度谷值所需的时间越短；射流温度的峰值基本出现在二氧化碳爆破器泄能的初始阶段，随后小幅度上升，再跌入谷值。射流升温的主要阶段在管内，二氧化碳爆破射流的温度总体呈现先上升后下降的趋势。

Abstract: In order to study the evolution law of the temperature field of carbon dioxide blasting jet, an infrared thermal imaging test system of carbon dioxide blasting was constructed, which enabled the space development and temperature evolution of the carbon dioxide blasting jet being analyzed through carbon dioxide blasting experiment. This paper will first introduce the principle of carbon dioxide blasting technology and the structure of carbon dioxide blasting device, and expound the physical properties of carbon dioxide. Through the operation of Span-Wagner equation of state, the relationship between temperature and pressure of carbon dioxide is revealed, and then the temperature-pressure relationship curve is drawn. Secondly, the evolution cloud map of jet temperature field is analyzed, showing that before the overtemperature phenomenon, the temperature gradient of the jet is the highest in the outer ring, slightly lower in the inner ring, and the lowest in the core region. While overtemperature occurs, the temperature gradient of the carbon dioxide jet is the lowest in the outer ring, slightly higher in the inner ring, and the highest in the core region. Therefore, the ambient temperature around the jet decreases first and then increases during the carbon dioxide explosion. Finally, the temperature-time curve of the jet is studied. One the one hand, the higher the initial discharge pressure, the higher the peak temperature of the carbon dioxide blasting jet, and the longer the time required to reach the peak temperature, with the highest temperature in the test reaching 133.7 ℃. While the lower the initial energy release pressure, the lower the temperature valley value, the shorter the time required to reach the temperature valley value, with the lowest temperature in the test being −3.4 ℃. On the other hand, the peak of jet temperature basically appears in the initial stage of blasting energy discharge, and then the temperature rises slightly, followed by the temperature drop to the valley value. The main stage of jet heating is in the pipe, and the study shows that the temperature of carbon dioxide blasting jet generally presents a trend of first rising followed by decreasing.
