Supporting data and reference code for surrogate-assisted industrial multi-fan allocation at equal estimated power

Supporting data and reference code for the manuscript "Surrogate-assisted fan allocation for industrial ventilation: Thermal and tracer trade-offs at equal estimated power" (manuscript v0.51). The study compares non-uniform fan allocations with same-scenario uniform references at equal estimated power in a normalized industrial hall. Regional temperature-rise and passive-tracer responses are evaluated using URANS and surrogate-assisted candidate screening. The archive contains processed regional responses, saved surrogate-model and decision records, sampled mean-field sections, reference geometry and input dictionaries, analysis and plotting code, figure PDFs, editable table definitions, and documentation linking files to the manuscript figures and tables. A file manifest and read-only structural inspection tools are included. The materials support inspection and reuse of saved results. Complete transient fields, the original volume mesh, restart fields and all solver logs are not included, so this package is not a complete workflow for rerunning the CFD study. Research code has been checked structurally after relocation; full execution and retraining have not been verified. The data are numerical study outputs, not field measurements. Licences apply by content type, not as alternative licences for the whole archive: original research data and specified documentation are under CC BY 4.0; the authors' own Python code is under MIT. Third-party notices and applicable terms are retained. The historical Shell reference recipe is outside the new Python-only MIT grant. See RIGHTS_SCOPE.md and the included licence files. Local preparation-status statements inside the archive describe the snapshot prepared on 22 October 2026; the repository record identifies its current deposit and publication status.
