Inflated mesh with full return path opening


12 deg Temperature rise.


This is less than the similar run 16 deg without inflated mesh, but this also has the correct si conductivity this time, so not yet know what was important for the change.


Input velocity 8 m/s

Exhaust velocity 9 m/s in center of path
