Abstract
The regulation of safety for Hydrogen gas station requires the temperature of Hydrogen gas lower than 85 ℃ during rapidly filling at high pressure into a FCV tank. Understanding of heat transfer in enclosed pressure vessels is important to achieve safe and rapid filling stations. In this study, temperature response on the wall of enclosed pressure vessel during filling Nitrogen gas was investigated experimentally. The stainless steel vessel was prepared and oriented horizontally with the inlet at the top. The temperature rises of the gas and the inner wall of the vessel was measured during filling Nitrogen gas at the pressure of 1, 3, and 5 MPa. Wall temperatures were measured at three positions on inner wall which were circumferentially putted top, side, and bottom. Heat transfer coefficient was obtained from measured temperature rise.
