Understanding Airflow Patterns - BIG ASS FANS Black Jack Guide D'installation

UNDERSTANDING AIRFLOW PATTERNS

You can treat air like water and scoop, direct, and channel it right where you need it most.
Airflow pattern with streamlined obstruction
Thin or streamlined obstructions do not block much airflow, regardless of size. The air tends to flow smoothly
around these obstructions, losing little momentum, and leaving only a small stagnant area behind the obstruction.
Airflow pattern with wide, blunt obstruction
A wide, blunt, or flat-faced obstruction forces the air to change direction, turning upward and outward. These
obstructions create a stagnant area behind them that is wider and higher than the obstruction itself.
Site recommendations
Consider the position of furniture, machinery, or other possible obstructions.
• Make sure people are not hidden behind structures that block airflow.
• Position large obstructions so their smallest profile is perpendicular to the direction of air movement.
• Position vertical structures in such a way as to scoop air into the area rather than deflect it.
