Figure 12.
The image contains two heat maps labelled a and b side by side. The left map a represents a variation of the field variable phi displayed across a grid pattern. The colour scale on the right ranges from blue to red, indicating values between 0.25 and 0.4. The right map b displays the saturation variable S w across a similar grid layout with its colour scale ranging from blue to red and indicating values between 0.55 and 1. Each map exhibits fluid transitions between colours to represent different values clearly, with both maps showing grid lines for reference. The layout allows for easy comparison between the two variables.Distribution of (a) porosity and (b) saturation degree at steady state for 20 mm sample size under condition HP2D.
