Abstract

We evaluated transport-aware tuning for membrane desalination under 44% salinity gradient. A deterministic paired simulation generated 64 cases and preserved a rare-condition slice. Mean flux-selectivity balance changed from 0.516 to 0.562; the paired difference was +0.046 (95% interval +0.044 to +0.049). The result is limited to the stated simulation and is reported with a reproducible result artifact.
