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.

Another approach in enhancing the light extraction efficiency of AlGaInP LED was accomplished using a surface roughening process. In this process, the Au(170 nm)/AuBe(260 nm)/Au(170 nm) ohmic contact layers were first deposited on the GaP window layer. After the alloy annealing process (480°C for 10 min), the Be atoms will diffuse into the GaP top layer and form non-uniform clusters. The LED samples were then immersed into a mixture 3H3PO4:1H2O2:1H2O solution for 6 min, resulting in a rough GaP surface. The luminous intensity of the AlGaInP LED can increase from 42 to 50 mcd, that is, an 18% enhancement can be achieved via the present non-photolithography surface roughening process.Keywords: LED, AlGaInP, Cu substrate, Reflector, Surface roughening
