# Fluids Module Guide

The Fluids module covers boundary layers, pipe flow, compressible flow, and CFD validation cases.

## Tabs

- **Boundary Layer** — Blasius laminar / log-law turbulent.
- **Pipe Flow** — Moody chart friction factor.
- **Compressible** — normal-shock tables, isentropic flow.
- **Vortex** — Taylor-Green decay validation.

## Canonical benchmark

Boundary-layer scan at Re = 6.8×10³ recovers Blasius δ/L = 5/√Re to better than 1% — automated test in `tests/fluids_validation.rs`.
