Data for "Linear Stability Analysis of Supercritical Water in Channel: Strongly Non-Ideal Effects"

This dataset contains processed numerical outputs supporting the figures, tables, validation tests, and Supplemental Material of the article "Linear Stability Analysis of Supercritical Water in Channel: Strongly Non-Ideal Effects." It includes equation-of-state and base-flow figure data, modal spectra and eigenfunctions, critical-layer locations, neutral curves, critical Reynolds-number scaling, modal and transient kinetic-energy budgets, non-modal optimal-growth results, wavenumber-parameter contours, numerical validation cases, and Supplemental Material animations. Data are primarily stored as MATLAB v5 `.mat` files, with selected `.csv`, `.xlsx`, `.fig`, `.png`, and `.gif` files. The numerical solver and license-restricted third-party software are not included.
