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.

Boyle's law is a law about gases. It states that if you increase the pressure on a gas, its volume decreases. This is like if you were to squeeze a balloon, the pressure of the air inside the balloon increases while the volume of the air decreases.
波以耳定律是关於气体的定律,该定律说明若增加气体的压力,气体的体积就会变小,这就像你若挤压一个气球,气球内空气的压力增加,体积却变小。

Environment radon is mainly from rock and soil in geological environment, but the research is not connected with geological environment now. On the basis of physical field, the theoretical distribution model of radon in soil and exchange model of earth—air are set up by using Fick diffusion law and Dacy law, and then the research of environment radon is linked with geological environment. This paper described how the evry parameter of the theoretical model influence the radon concentration in air. The results of research indicat that molecule diffusion of radon is different from it's eddy form. Under the condition of surface radon source, the model experiment is used to study the transportation and distribution of radon in medium. The data of experiment show the relationship between radon and depth can be described by exponent. If the radioelement is well—distributtion, the concentration of radon in different depth or in different point at the same depth change with time, but the accumulated exhalation amount of radon at different point on the surface of model are close in relative long time. The author studied the exchange of radon between mediums and verified the theoretical models too.
环境氡主要来自岩石、土壤,而目前环境氡研究中与地质环境结合很少,为此作者以物理场为基础,运用气体运移的费克扩散定律和达西定律,建立起壤中氡浓度分布与大地—大气间氡交换理论模型,首次在理论上将环境氡与地质环境结合起来;论文中从理论上讨论了模型中各参数对空气中氡浓度的影响,发现空气中氡运移的分子扩散方式和湍流扩散方式存在明显差异;通过面状氡源条件下的氡运移模型实验,研究了介质中氡的运移与分布,实验数据表明氡浓度随深度的变化规律可用指数函数描述,在放射性元素分布均匀的条件下,介质中不同深度和同一深度不同点的氡浓度随时间而变,但介质表面不同点在较长时间内向空气中累计释放的氡的量是相近的;同时研究了不同介质间氡的交换,并验证了所建立的理论模型;运用理论模型预测青岛市城区壤中氡浓度、江西临川一住宅区空气中氡浓度及江西二个测区的区域空气中氡浓度分布,取得了较好的效果。
