在熔融相冶金过程中,注入气体进行混合对于获得均质产物至关重要。混合效率取决于气体流速、渣层高度以及熔融相物理性质等工艺参数。本文通过数值模拟研究底吹浴槽中流体行为的上述参数。用水和油分别模拟熔融金属和熔渣,根据实验数据对数值模拟结果、特别是混合时间进行验证。结果表明,混合时间随渣层高度增大而增加,随炉渣材料密度增加而减小。混合时间随主相密度的增加而减小,随着空气和水间表面张力的增大而增加。还模拟一种性质接近真实熔融金属的情形。系统的行为主要受动量的影响,而不是受耗散力的影响。因此,与空气和熔融相间表面张力的影响相比,熔融相密度对混合过程的影响更为显著。

BACKGROUND: Post operative sore throat (PST) is one of the most common complaints after tracheal intubation. In this study we compared the effects of curved and straight laryngoscope blades on severity and incidence of PST. METHOD: In this prospective randomized clinical trial we evaluated incidence and severity of PST in 147 ASA physical status I–II, aged 18 – 62 y (group Miller, n = 71), (group Macintosh, n = 76) following intubation with Miller and Macintosh laryngoscope blades by using Visual Analog Scale (VAS). RESULTS: The overall incidence of PST in our study was 35.4% (Macintosh group = 39.5% and in Miller group = 31% and P = 0.829). The incidence of PST was not statistically different between two kinds of laryngoscope blades and the mean rank of pain score was not statistically different in recovery room and up to 48 hours after surgery. CONCLUSIONS: Our study showed these types of laryngoscope blade had not association with incidence and severity of PST. .
