Standards catalog

Validation: indicative · Method band: advanced-numerics

Indicative method: Indicative closed-form or numerical model

Linear elastic material behavior unless noted otherwise.

Purpose: Thermal duty, LMTD, NTU, effectiveness for parallel/counterflow.

Method: Advanced numerics / correlations

\dot{Q} = \overset{m}{˙}_{h} c_{p, h} (T_{h, in} - T_{h, o u t}), LMTD = \frac{Δ T _{1} - Δ T _{2}}{ln ( Δ T _{1} /Δ T _{2} )}

ε = f (NTU, C_{r}), NTU = \frac{U A}{C _{min}}

UI: Legacy layout; unit profile.

Gaps: No pressure drop or fouling; fixed flow arrangements; draft-adjacent maturity (indicative catalog).

Maintainer note: Thermal correlations and iterative steps benefit from core reuse.
