Turbulence Sphere

About Turbulence Sphere

Overview

A precision sphere model designed for studying boundary layer transition and critical Reynolds number in wind tunnel testing. With a highly polished surface and no pressure taps, the model relies on force (drag) measurements to identify flow regime changes with high accuracy.

 Key Features

• Ideal for Transition Studies: Determines critical Reynolds number via drag data
• Highly Polished Surface: Ensures consistent and repeatable results
• Simple Geometry: Minimizes complexity in data interpretation
• Sting Mounted: Standard 3/8-inch mounting post
• Multiple Sizes Available
