在分析南海海洋气象观测现状和发展规划的基础上,发现有必要发展合适的资料同化技术,提高资料利用效率,才能克服海洋气象资料相对缺乏来提升数值预报水平。利用多尺度/分块逐批资料同化技术,进行热带气旋资料同化试验。结果表明:多尺度/分块逐批资料同化技术能够适应具有多尺度特征的热带气旋资料同化,较好地满足热带气旋资料同化对流依赖背景误差协方差同化技术的要求,能够较合理高效地利用海洋气象观测资料。基于多尺度/分块逐批资料同化技术,加强海洋气象观测系统的应用,是形成高质量热带气旋初值环流的一种有效途径。

利用雷诺应力模型(RSM)对直切单入口、直切双入口、斜切单入口、斜切双入口、斜切螺旋面单入口、斜切螺旋面双入口6 种不同侧向入口旋风分离器内部气相流场进行了计算分析。结果表明:双入口结构旋风分离器内部压力场和速度场具有更好的对称性与稳定性;仅改变入口斜切角度对旋风分离器内部速度场和压力场的分布影响不大;当本文中6 种分离器内部具有相近的切向速度径向分布时,斜切螺旋面入口结构分离器压力损失减少约25 %,入口所需总压降低17 %,处理相同气体量的能耗约下降17 %;斜切螺旋面双入口(XS-L型)分离器是一种综合性能比较优的旋风分离器。

During the operational phase, building performance may decrease in various areas, so that the end users’ requirements are no longer met. Consequently, indicators are useful to assess and improve the performance of existing buildings. In this study, we carried out a literature review and organized a focus group with facility management experts to gather and analyze facility managers’ perceptions on operational indicators that could be used to assess the performance of buildings. The results revealed that the core indicators used to measure a building’s operational performance are related to safety and assets working properly, health and comfort, space functionality, and energy performance. The findings also revealed that these indicators can be obtained from three sources: a) facility managers/operators, who carry out corrective maintenance and perform technical inspections, b) regular users, who report complaints and fill-in satisfaction questionnaires, and c) sporadic users, who also fill-in satisfaction questionnaires. These indicators and their sources can contribute to a better analysis of building performance and the definition of measures to improve performance during the operational phase of a building.
