ThermoForge HX

First-launch legal gate: bilingual EULA & Privacy Policy acceptance with versioned consent tracking. Calculation Engine Correction of the F factor for crossflow: now derived from NTU_counter / NTU_arrangement (previously, it was an incorrect approximation that reused the 1-2 shell-and-tube formula). New TEMA RGP-T-2.4 fouling table with values for 11 fluids, scaling factors by service class (R/B/C) and side (tube/shell). Shell-side pump power now displayed by the engine (previously recalculated manually in the Econ tab). Tube-side ΔP limits keyed by TEMA class: R=70, B=100, C=200 kPa. Honest GUI Sim: the “Bell-Delaware” label becomes “Kern (fallback)” when the engine falls back on the simplified correlation. Stats: “Balanced” pill driven by actual imbalance; thermal profile caption follows the chosen arrangement. Foul: “month 4 of 36” pill replaced by “projection · 4/36 mo” (static, honest). Sim: removed the misleading claim “iterates until residual — now “closed-form ε-NTU + Bell-Delaware”. Shared status Design pressure and TEMA class now unified between Datasheet and Mechanical. Absolute/Gauge toggle propagated everywhere with suffix “bar a”/“bar g”. Fixed double ASME B16.5 conversion on flanges. Volume tab: tubeSide-aware dispatch, corrected Imperial step, unified theme. PDF/CSV Report Heat duty unified to Q_avg (standard for the engine). Added pump power tube + shell, shell method, confidence balance.
