bibo:abstract
  • In this study, thermal diffusion caused by using air cooled condenser at LNG power plant in Yulchon was simulated through in numerical method (Matsuno scheme). The input data of model was used to seasonal wind components (u, v) of automatic weather system (AWS) and seasonal temperature ranges between inflow and outflow of opening air. The aim of this study was twofold : (1) to investigate sensibility analysis of thermal diffusion coefficient : (2) to simulate diffusion of heat source through the calculated effect height for season and stability variations. These sensibility analyses were performed in detail using two case studies one is to apply horizontal and vertical thermal diffusion coefficient as 50 <TEX>$$m^{-1}$$</TEX><TEX>$$s^{-1}$$</TEX> and 10 <TEX>$$m^{-1}$$</TEX><TEX>$$s^{-1}$$</TEX>, the other is 30 <TEX>$$m^{-1}$$</TEX><TEX>$$s^{-1}$$</TEX> and 10 <TEX>$$m^{-1}$$</TEX><TEX>$$s^{-1}$$</TEX> respectively. It is well known that the sensibility for thermal diffusion coefficient is low owning to very similar results. Consequently, thermal diffusion for the first case is simulated by using effect height for season and stability variation. The temperature is under 1℃ at surface whereas that is high at near the center of effect height. (rdf:langString) (en)
