We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

At 950m/s I suspect it's turbulent!  The various turbulence models add additional terms into some (all?) of the equations, and these can be more stable than invisid or laminar flows as gradients tend to be marginally smoother. If you've got reactions on, how would the chemistry differ?
