Ethanol-Water (UNIQUAC) VLE validation vs. experiment

within tolerance

MaximaLabs reproduces the ethanol/water vapor-liquid equilibrium under the uniquac property package and measures the deviation from published experimental data — live, on every page load, never a pinned number.

Model vs. experiment

The solid curve is the UNIQUAC model; the amber markers are the cited experimental points.

Re-execute this validation on our server right now — it reproduces the published AAD exactly (the model is deterministic; only the wall-clock varies).

Reproduce this number

We publish our inputs, our numbers, and the citation so the comparison is reproducible. To benchmark another simulator, build the identical ethanol/water case in it under an equivalent property method and compare against the cited reference — the ground truth both are measured against. We don't publish competitor numbers we didn't measure.

uv run python scripts/reproduce_validation.py   # recomputes every number live
