제목 N2 flow rate effect on hydrodynamics of low temperature furnace for continuous carbonization of carbon fiber
초록 Hydrodynamic characteristics of a low temperature furnace (LTF) for Polyacryclonitrile (PAN)-based fiber carbonization were investigated by a gas phase 3-dimensional (3D) computational fluid dynamics (CFD) model. Thirty PAN-fiber tows moving at a constant speed were considered as porous media. The porous media model parameters, such as porosity and viscous resistance, were calculated with respect to a zone-dependent off-gas emission model with eight species. Velocity, temperature and concentration profiles along the furnace length were examined according to various N2 inlet flow rates. The off-gas residence time (τres), dead-zone (or stagnant gas region) ratio (χ), temperature uniformity index (UIT) and vorticity (ξ) were used as performance criteria of the LTF. An optimal N2 flow rate was determined, compromising the four performance criteria.
