PROJECT Example

Tornado Research at Missouri University of Science and Technology

Setup

For a research program on tornado dynamics, Missouri S&T used Vectoflow Omniprobe and 5-hole probes to study how hills and slopes influence tornado paths and vortex structures under controlled wind tunnel conditions.

Challenge

Capturing precise, multi-directional flow data in highly turbulent, tornado-like vortices to understand how topography alters wind speed, pressure deficits, and vortex behavior.

Key Findings

Significant changes in horizontal, lateral, and vertical wind velocities near hilltops
Terrain strongly influences tornado path shifts and intensity
Vectoflow probes enabled accurate, repeatable data even in complex, unsteady flow fields
