项目摘要

In this research organization, research on the real phenomenon reproducibility by using the unsteady CFD analysis technique was done for the purpose of the application to the next-generation environmental design of the analysis technique for air flow and thermal environment. Before dealing with an unsteady phenomenon, accuracy of CFD analysis was mainly verified in 2003. The accuracy of CFD analysis was verified following the preceding year, and the LES database was created based on the examination result in 2004. In 2005, experiment and survey for the unsteady air-conditioning interior of a room were performed, and accuracy verification and practical use possibility of the analysis technique of air-flow were examined. The result outline acquired by this research is shown below.・In examination of the prediction technique of the analysis by LES, CFD analysis by LES and k-e was carried out for non isothermal indoor air-flow in which the buoyancy effect excelled, and the validity and the predominancy of LES were checked. Consequently, LES showed that it was the practical prediction technique also on the business level.・While performing ventilation performance evaluation of the inflow opening based on a local similarity model, the wind tunnel experiment was conducted about the opening of various forms for the purpose of creating the design data for calculation of the amount of ventilation, and the ventilation performance database was created.・the environment resulting from regular design and that resulting from movable-nozzle design were compared using LES. ADPI, an indicator of the conditions in the occupied zone during air conditioning, was calculated, and confirmed the effectiveness of air conditioning using movable nozzle outlets.・The building circumference wind pressure distribution by the improvement k-e model which introduced limiter proposed by Durbin was predicted, and optimization of the model parameter based on comparison with an experiment was reported.

在这个研究组织中，通过使用Unsteady CFD分析技术对真实现象可重复性的研究是为了将空气流和热环境分析技术的下一代环境设计应用于应用。在处理不稳定现象之前，主要在2003年验证了CFD分析的准确性。在前一年之后，CFD分析的准确性得到了验证，并且根据2004年的检查结果创建了LES数据库。2005年，2005年的实验和调查，对不稳定的空调内部进行了实验和精确的验证，并进行了实践，并进行了实践，并进行了实践，并实践了实践。这项研究获得的结果大纲如下所示。・在检查LES和K-E分析的预测技术时，对非等温室内空气流进行了CFD分析，其中浮力效果极好，并且检查了LES的有效性和优势。因此，LES表明，这也是业务水平上的实际预测技术。・在基于局部相似性模型进行通风性能评估时，对开放进行了通风性能开放，但进行了有关开放的各种形式的实验，目的是为创建设计数据以计算用于通风量的设计数据，并使用频繁的数据库进行了量化的设计。计算了空调过程中占用区域条件的指标ADPI，并确认了使用可移动喷嘴出口的空调的有效性。・ the Building Circle circe circe circe requation the the Revermement k-e模型介绍了Durbin提出的限制器，预测了Durbin提出的限制器，并报告了基于与实验的模型参数的优化。
