Figure 7.
The graph illustrates the relationship between the normalised distance from the injection boundary denoted as y divided by l and the mass flux ratio of gas phase hydrogen to hydrogen represented as f H 2 divided by f H 2. The x axis ranges from 0.95 to 1, while the y axis ranges from 0 to 1. Data for four different square areas specified as 10 by 10 millimetres squared, 20 by 20 millimetres squared, 40 by 40 millimetres squared, and 80 by 80 millimetres squared are depicted using different line styles, solid, dashed, dash dotted, and dotted respectively. The curves demonstrate a gradual approach towards the injection boundary with all lines converging near the upper limit on the graph.Profile of mass flux ratio of gas-phase hydrogen to hydrogen from the gas injection boundary to the back pressure boundary of the sample for different sample sizes under condition HP2D. The distance is normalised by the sample size, l. The hydrogen mass flux includes gas-phase hydrogen and dissolved hydrogen
