In this paper, we consider the two‐dimensional chemotaxis‐Navier‐Stokes system with singular sensitivity
in a bounded convex domain Ω ⊂ R2 with smooth boundary, with κ ∈ R and a given smooth potential ϕ : Ω → R. It is known that for each κ ∈ [0, 1) and 0 < χ < 1 this problem possesses a unique global classical solution (nκ, cκ, uκ). Our main result asserts that under the assumption of 0 < χ < 1, (nκ, cκ, uκ) stabilizes to (n0, c0, u0) with an explicit rate and a time dependent coefficient as κ → 0+.
