Figure 9.
The graph displays the relationship between the mass flux ratio of gas phase hydrogen to hydrogen denoted as f H 2 divided by f H 2 on the horizontal axis ranging from 0.95 to 1, and the vertical axis representing the normalised distance from the injection boundary y divided by y i which ranges from 0 to 1. Three line styles represent different f values, solid for f equals 0.25, dashed for f equals 0.322, and dotted for f equals 0.4. The graph indicates a distinct trend in normalised distance with changes in mass flux ratio across the specified f values, showcasing a sharp decline at specific mass flux ratios.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 20 mm sample size under condition HP2D with different porosities
