Abstract
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 $\small{{\pm}0.6%}$. In light of flow characteristics, the rectangle type tube and the type 2 with $\small{45^{\circ}}$ turn showed most uniform flow characteristics and concentration distribution of methanol, and the circular type tube and the type 3 with $\small{90^{\circ}}$ 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 $\small{45^{\circ}}$ as in the type of curved pipe with $\small{45^{\circ}}$ turn.
