Why use CFD?

Analysis and Design

1. Simulation-based design instead of “build & test”

More cost effective and more rapid than EFD

CFD provides high-fidelity database for diagnosing flow field

2. Simulation of physical fluid phenomena that are difficult for experiments

Full scale simulations (e.g., ships and airplanes)

Environmental effects (wind, weather, etc.)

Hazards (e.g., explosions, radiation, pollution)

Physics (e.g., planetary boundary layer, stellar evolution)

Knowledge and exploration of flow physics
