디젤기관에서 흡기습도가 연소에 미치는 영향에 관한 연구
탁영조,하종률 동아대학교 공과대학 부설 한국자원개발연구소 1992 硏究報告 Vol.16 No.1
It is important to reduce Smoke and NO_(x) which are a serious problem in the Diesel Engine. Thus, many studies for this problem have been performed. In this study, in order to obtain the information for the influence of inlet humidity on the combustion in the Diesel Engine, Combustion Characters, Engine Performace and Exhast gas emissions are analyzed experimentally.
디이젤 機關에서 排出되는 微粒子의 測定方法에 관한 硏究
卓泳祚,崔東憲,河鍾律 東亞大學校 大學院 1987 大學院論文集 Vol.12 No.-
The Mini-dilution tunnel has been designed and constructed for the diesel particulate emission measurement and in order to reduce the pariculate emission from diesel engines. In this system, raw exhaust is split off and then diluted in the tunnel with air to control the mixture temperature and the CO₂ tracer method is used to determine the dilution ratio for the calculation of particulate mass fraction For designing this system, experimental data relative to tunnel diameter, length, volume flow, mixture temperature degree of mixing and sampling flow rate were reviewed. Concequently, this mini-dilution tunnel system was found to have a good correlation with a larger dilution tunnel.
P-904 : Heterostructures of ultrafine ZnO nanorods and carbon-coated SiC nanowires
탁영조,류용환,용기중 한국화학공학회 2007 화학공학의이론과응용 Vol.10 No.2
Ultrafine ZnO nanorods can be directly grown on carbon-coated SiC nanowires using metalorganic chemical vapor deposition at temperatures of 500~600℃. First, carbon-coated SiC nanowires were fabricated on NiO catalyzed Si(100) in a WO3 and C carbothermal reduction environment. The diameter range of SiC nanowires was 20~50nm. We flowed DEZn source for 1~2 hours on the SiC nanowires, then ZnO nanorods were grown on the surface of SiC nanowires without the presence of a catalyst. The diameter range of ZnO nanorods was 7~20nm. Heterostructures were analyzed by SEM, EDS, TEM, XRD.
