The main work and the originality points of this dissertation could be concluded as the following parts:(1) To analyze systematically the mathematical model of LES of air flow in great space, under the case of isothermal and non-isothermal, as well as the combined action of buoyancy and strain. Some basic problems are studied about the LES application into airflow simulation of great space, such as boundary conditions, spatial difference scheme and time advancing scheme, time step etc., which creates the basis for the LES application to indoor airflow simulation.(2) Both the instantaneous and time averaged flow field of great space with multiple jets under isothermal and non-isothermal cases are explored with large eddy simulation method, and also discussed the dynamic characteristics and the law of fluidflow in the great space.(3) Based on the results of LES of the great space and the Fanger thermal comfort indexes, it is brought forward the concept of the series of dynamic thermal comfort evaluating indexes, which could be divided into thermal comfort index with time averaged properties PD, PPD, PMV, thermal comfort index with instantaneous properties IPD, IPPD, IPMV, and time averaged thermal comfort indexes TAPD, TAPPD, TAPMV, and transient situations time averaged thermal comfort indexes TTAPD, TTAPPD, TTAPMV. The differences among them and the calculation methods are discussed, and the four kinds of indexes are calculated with the thermal comfort index PD as an example.(4) Based on the LES results it is discussed the hot air stratification phenomena in air-conditioned buildings in the case with air supply and return registers on the ceiling and the case on the sidewall. The fundamentals of the hot air stratification are studied and the relations of estimating hot air stratification are brought forward.(5) With the advanced apparatus such as hot wire film anemometer IFA300 and laser particle field anemoscope, corresponding model test and site measurements have been done, which are compared with the simulation results and LES is proved a very promising method in air flow simulation indoor.

本文主要工作既创新点体现在以下几个方面：(1)系统分析了等温、非等温和考虑剪切力与浮升力综合作用的高大空间大涡模拟数学模型，并研究了高大空间大涡模拟在室内气流仿真应用中的一些基本问题，如边界条件、空间离散格式和时间推进格式、时间步长选择等问题，为大涡模拟在室内气流计算中的广泛应用打下了基础；(2)首次用大涡模拟方法研究了高雷诺数下高大空间多射流在等温、非等温情况下的瞬时流场和时均流场分布，并探讨了多射流流场的动态特性和流动规律；(3)基于大涡模拟的动态仿真结果和Fanger的热舒适指标，首次系统地提出了动态热舒适评价指标体系的概念：即基于时间平均参数的热舒适指标PD、PPD、PMV；基于瞬时参数的瞬时热指标IPD、IPPD、IPMV；基于时间平均热舒适指标TAPD、TAPPD、TAPMV；以及沿行动迹线的时间平均热舒适指标TTAPD、TTAPPD、TTAPMV，并分析了四类热舒适指标的差异性和计算方法，还以PD值为例对四类指标分别进行了计算；(4)基于数十种工况下空调房间大涡模拟的结果，研究了空调建筑上送上回和侧送侧回两种情况下热分层现象，并探讨了热分层的基本规律，首次提出了避免热分层现象的判断公式；(5)在暖通空调领域，首次使用IFA300热线风速仪、激光粒子速度场仪等先进设备，完成了与大涡模拟相对应的模型试验，并把实测结果与仿真结果进行了对比，说明LES在室内气流仿真方面是一种很有前景的方法。

The Activated Ploy-oxygen Aerator adopts magnetic engineering technology to send the oxygen of air which is gathered and activated by polyoxier to the mixing chamber of main engine under water, and the process of water and oxygen synthesization is finished rapidly by the use of magnetizer and activated oxygen enriched air under water, which has been cut into tiny air bubbles by the high-speed rotated propeller of the mixing chamber in the process of water and oxygen synthesization, which can increase the affinity of water and oxygen. When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.

聚氧活化曝气增氧机采用磁性工程技术，将空气中的氧经聚氧器聚集活化后送到水下主机的混合室，由水下的磁化器和活化富氧空气快捷完成水气合成程序，在水气合成过程中已被混合室内高速旋转的离心叶轮切割成微小气泡，这些随射流、射向水下方的小气泡，其动能消耗至零后，在水中的浮力作用下、开始缓慢上升，由于提高了水与氧亲合力的小气泡只靠浮力沿着螺旋型的曲线缓慢浮升，这些小气泡在短时间很难浮上水面，因此延长了小气泡在水中的停留时间和行走路程，大大提高水中溶解氧的效率，使该机的动力效率明显高于传统曝气装置。
