NUMERICAL MODELING ALGORITH FOR METAL HYDRIDE TANK INTERPRETATION

摘要

PURPOSE: An algorithm of a numerical model for metal hydride alloy tank interpretation is provided to produce a temperature, a reaction rate, and a change of hydrogen concentration of MH alloy according to hydrogen reaction only with numerical model calculation for various types of MH alloy tanks, thereby removing various aspects of constraints such as device manufacturing costs, experiment costs, or time. CONSTITUTION: An initial hydrogen concentration within MH alloy, an initial temperature and an initial reaction velocity value are inputted. A residual hydrogen concentration within the MH alloy depending on reaction flow is calculated, and a reaction temperature according to heat of reaction depending on the reaction flow is calculated. The reaction flow is calculated at a fixed time interval defined by formula 2. The residual hydrogen concentration calculation step, the reaction temperature calculation step, and the reaction flow calculation step are repeated according to an interpretation period and the time interval.
