Conclusion

Why the results are comparable

Every model captures the steep heat-flux fall away from the stagnation point. The non-catalytic cases sit below the ELECTRE measurements, while catalytic and multi-temperature treatments move the magnitude toward the experiment; the 2-T and 3-T curves are nearly indistinguishable over most of the skin.
