Study on Methanol Conversion Efficiency of Steam-Methanol Reforming on Pipe Shape and Flow Rate Variation in Curved Channel Seong, Hong Seok; Lee, Chung Ho; Suh, Jeong Se;
This is a numerical study on the curved channel type of hydrogen reformer using the commercial code of fluid dynamics. We numerically compared the numerical model in a previous study model and the modelling of a tube type curved channel. In the result of numerical analysis on 4 types of curved channel reformers, the methanol conversion efficiency of type 1~4 were 45.0%, 45.3%, 45.6%, 45.6% respectively, and there was hardly any difference by . In light of flow characteristics, the rectangle type tube and the type 2 with turn showed most uniform flow characteristics and concentration distribution of methanol, and the circular type tube and the type 3 with turn had most un-uniform flow characteristics and concentration distribution of methanol. We concluded that the design for curved channel reformer has to have rectangle type tube with curve of almost as in the type of curved pipe with turn.
