A numerical study of supercritical CO_(2) two-phase flow in the ejector was carried out by computational fluid dynamics(CFD) methods. Through the comparison of simulation results and available experimental data in the literature, the accuracy of the three-dimensional CFD model was verified. A comparison of the effects of four turbulence models on the simulation calculation results was also presented. The distributions of pressure, velocity, two-phase volume fraction, shock wave and exergy flux inside the ejector were analyzed. The effects of the mixing section geometry on the performance of the ejector were obtained. Then, the entrained performance of the ejector was investigated by changing the area ratio between the constant-area mixing chamber and the outlet of the motive nozzle(AR) and the ratio between the length and the diameter of the constant-area mixing chamber(LDR). Finally, the optimum AR and LDR were determined to be 8.3 and 8.1, respectively based on the maximum entrained ratio and the minimum exergy destruction. Through optimizing the mixing chamber geometry, the minimum total exergy destruction and the maximum mass entrainment ratio(MER) of the ejector can attain 0.33 J/(kg·K) and 0.698, respectively.

2022年北京冬奥会的举行促使我国的人工冰场迅速发展。运用数模拟的方法对直接蒸发式人工冰场进行传热模拟,研究了防冻管温度、冰面温度、供冷管间距等因素对供冷管热流密度及温度、冰面温度均匀性的影响。结果表明,防冻管温度的变化对冰面温度的影响可以忽略;冰场供冷管内工质的蒸发温度为-32.000~-22.400℃;冰面温度降低1.000℃,冰场冷负荷增加5.90 W/m^(2),供冷管内工质的蒸发温度降低1.200~1.500℃;随着供冷排管间距的增加,供冷管内工质的蒸发温度和冰面温度均匀性下降;间距从30增加到60 mm,冷管内工质的蒸发温度降低15.9%,冰面温度不均匀性指标温差最值从0.004增加到0.111℃。

窒息氧合是指患者在没有自主呼吸或机械正压通气的情况下血液从肺部摄取氧气维持氧合。在全麻实施过程中,诱导后自主呼吸停止而安全的气道未建立之前,使用窒息氧合能在预充氧的基础上延长患者的安全呼吸暂停时间,从而减少气管插管的尝试次数,降低气道损伤以及低氧血症、血流动力学失代偿的发生率。近十年来,越来越多的窒息氧合技术已经被应用于不同的临床环境中,如围术期的气道管理和“无管麻醉”等。为进一步加深对窒息氧合的认识和了解其应用范围,本文根据现有关于窒息氧合机制、方法及临床应用的最新研究进行综述,为临床应用提供参考。
