-Abstract
This study focuses to the heat absorption measurement of Endothermic Fuel (EF). From the view point of the easy operation, the methanol is chosen as the EF with lower endothermic reaction temperature. The endothermic reaction of methanol is caused at about 573 K by using a nickel catalyst. The experimental apparatus was verified first by water as a working fluid before the experiment using the methanol. The characteristics of the experimental apparatus such as the heat transfer and the pressure loss were obtained by the pre-experiment by using water, although the endothermic reaction is not taken in account at the water experiment. It was made it clear that the heat transfer coefficient of main heater was laid within 80 ~ 120 % of the analytical value by using water. It can be concluded from the pre-experiment using water that the temperature. In addition, the improvement of the experimental apparatus is proposed for the experiment of the methanol.
Keywords : Endothermic Fuel, Endothermic reaction, Heat Absorption Measurement, Methanol
