Fluid flow

Built on it

• Aerospace (aircraft) — Aircraft teaching sheets for PartCraft: wing lift, stall and induced drag, weight and balance, and the published 4-digit airfoil thickness and camber formulas.
• Data center and mission-critical facilities — HVAC, energy and risk items for BimCraft with four calculation sheets: PUE, rack airflow and cooling units, UPS battery energy and redundancy availability.
• Mechanical (HVAC) engineering — HVAC and piping add-ons, building energy and regulation packs for BimCraft and CadCraft, with four calculation sheets: supply airflow, round duct, fan power and hydronic flow.

Use it in your add-on

Name it in your manifest's needs. When someone adds your add-on, their account brings this engine too, and every edition loads it the first time your add-on needs it. Version ranges arrive with AL.13.

Methods and standards

Marker-and-cell staggered grid, a projection step, a hybrid convection scheme and a van Leer limited scalar, all from published papers named in the file header.

Limits

Planned. Laminar flow only, so it cannot predict turbulent mixing. A calculation aid: an engineer checks every result.
