Small Steps, Large Changes…

A vertical shock tube at Los Alamos National Laboratory is used for turbulence studies. Sulfur hexafluoride is injected at the top of the 5.3-meter tube and allowed to mix with air. The waste is ejected into the environment through the blue hose at the tube tower’s lower left; in the fiscal year 2021, such emissions madeContinue reading “Small Steps, Large Changes…”
