Abstract
A model was proposed to estimate a temperature change during filling. It verifies to be a good agreement between the measured and estimated temperatures of hydrogen in a wide range of charging conditions. Seven non-dimensional parameters, which govern the temperature change, are derived from the governing equations. One of them is a controlled one related to the pressure change or mass flow rate. Some case studies have been done based on a corresponding filling test using actual tanks. The effect of two parameters of them on the temperature characteristics is explained as a example.
