Composite Wall Test-chamber Assessment for Hydrogen Blast Loads

Simplified energy based analytical models are used to evaluate the quasi-static and impulsive over-pressure responses of blast resistance composite wall test-chamber for different hydrogen charges, which is validated with experimental observations during hydrogen combustion tests. Further a detail three-dimensional transient finite element simulation of the test-chamber is presented to compare the test results with the finite element results. The effectiveness of evolved procedures is highlighted for the blast resistance evaluation of experimental facilities besides the other infrastructures that might be subjected to hydrogen blast loads.
