“…Additionally, radiative heat loss on the cylinder wall is also taken into account, using surface emissivity of 0.5. At the internal wall, the heat exchange rate between the hydrogen gas and the plastic liner is represented by a heat transfer coefficient of 1000 W/m 2 /K [12]. …”

“…In this study, the fire resistance is predicted by monitoring the internal pressure and the time at which the failure pressure of 357 bar is reached. We predict the internal pressure increase using the following equation on internal pressure-temperature relation fitted from a fire experiment on a type-IV cylinder [12]: p =1.2T + 320 (6) In the above equation, p is in bar and T is in 0 C.…”

“…The thermal response of polymer composite for general application has been extensively modelled [5][6][7][8][9], taking into account a number of important physical and chemical aspects, such as thermal decomposition reaction of the CFRP, the transport of volatile gas towards the heated surface, pressure rise in the CFRP, and thermal expansion/contraction. For onboard hydrogen storage application, numerical models have been employed to study the hydrogen cylinder behaviour subjected to both engulfing fire [10,11] and localized fire [12][13][14].…”

With the anticipated introduction of hydrogen fuel cell vehicles to the market, there is an increasing need to address the fire resistance of hydrogen cylinders for onboard storage. Sufficient fire resistance is essential to ensure safe evacuation in the event of car fire accidents. The authors have developed a Finite Element (FE) model for predicting the thermal response of composite hydrogen cylinders within the frame of the open source FE code Elmer. The model accounts for the decomposition of the polymer matrix and effects of volatile gas transport in the composite. Model comparison with experimental data has been conducted using a classical one-dimensional test case of polymer composite subjected to fire. The validated model was then used to analyze a type-4 hydrogen cylinder subjected to an engulfing external propane fire, mimicking a published cylinder fire experiment. The external flame is modelled and simulated using the open source code FireFOAM. A simplified failure criteria based on internal pressure increase is subsequently used to determine the cylinder fire resistance.

“…A localized heat impingement experiment for a type 3 tank was carried out by Powertech labs [13]. Hu et al [14] studied thermal damage of the composite tank subjected to localized flame impingement based on a 2D axisymmetric finite element model. Ruban et al [15] carried out the localized fire exposure burst test and showed that the tank burst after 5 min 20 s of fire exposure.…”

“…Using the finite element method as a numerical tool, numerous studies have been conducted on high-pressure storage cylinders [7][8][9]. Compared to pure mechanical loading, fewer studies have been conducted on composite hydrogen storage cylinders subjected to thermal loads and combined thermo-mechanical loads [10][11][12].…”

Safe installation and operation of high-pressure composite cylinders for hydrogen storage are of primary concern. It is unavoidable for the cylinders to experience temperature variation and significant thermal input during service. The maximum failure pressure that the cylinder can sustain is affected due to the dependence of composite material properties on temperature and complexity of cylinder design. Most of the analysis reported for high-pressure composite cylinders is based on simplifying assumptions and does not account for complexities like thermo-mechanical behavior and temperature dependent material properties. In the present work, a comprehensive finite element simulation tool for the design of hydrogen storage cylinder system is developed. The structural response of the cylinder is analyzed using laminated shell theory accounting for transverse shear deformation and geometric nonlinearity. A composite failure model is used to evaluate the failure pressure under various thermo-mechanical loadings. A back-propagation neural network (NNk) model is developed to predict the maximum failure pressure using the analysis results. The failure pressures predicted from NNk model are compared with those from test cases. The developed NNk model is capable of predicting the failure pressure for any given loading condition.
