Paper: Effects of Numerical Resolution on Simulated Cloud-Wind Interactions
What they're saying
Cloud survival and velocity depend strongly on numerical resolution.
The Critique
The finding that supersonic cloud destruction requires higher resolution than growth has implications for galaxy formation simulations, but they don't quantify how this affects observational predictions. If unresolved simulations systematically misestimate cloud lifetimes, this could bias star formation rate predictions.
Why It Matters
Galaxy formation simulations routinely use sub-grid models for unresolved processes. If cloud destruction is systematically under-resolved, this could propagate into incorrect predictions for the cosmic star formation history.
What They Missed
They don't address whether their results apply to 3D (their study is 2D)â3D turbulence may have different convergence properties.
