This paper is concerned with the following Keller-Segel-Navier-Stokes system with signal-dependent diffusion and sensitivity

$\begin{cases}\tag{*}n_t+u·\nabla n = \nabla ·(d(c)\nabla n)-\nabla ·(χ (c) n\nabla c)+a n-bn^2, &x∈ Ω, ~~t>0, \\ c_t+u·\nabla c = Δ c+ n-c,&x∈ Ω, ~~t>0, \\ u_t+ u·\nabla u = Δ u-\nabla P+n\nabla φ,&x∈ Ω, ~~t>0, \\\nabla · u = 0& x∈ Ω, \ t>0, \end{cases}$

in a bounded smooth domain

$Ω\subset \mathbb{R}^2$

with homogeneous Neumann boundary conditions, where

$a≥0$

and

$b>0$

are constants, and the functions

$d(c)$

and

$χ(c)$

satisfy the following assumptions:

●

$(d(c), χ (c))∈ [C^2([0, ∞))]^2$

with

$d(c), χ(c)>0$

for all

$c≥0$

,

$d'(c)<0$

and

$\lim\limits_{c\to∞}d(c) = 0$

.

●

$\lim\limits_{c\to∞} \frac{χ (c)}{d(c)}$

and

$\lim\limits_{c\to∞}\frac{d'(c)}{d(c)}$

exist.

The difficulty in analysis of system (*) is the possible degeneracy of diffusion due to the condition

$\lim\limits_{c\to∞}d(c) = 0$

. In this paper, we will use function

$d(c)$

as weight function and employ the method of energy estimate to establish the global existence of classical solutions of (*) with uniform-in-time bound. Furthermore, by constructing a Lyapunov functional, we show that the global classical solution

$(n, c, u)$

will converge to the constant state

$(\frac{a}{b}, \frac{a}{b}, 0)$

if

$b>\frac{K_0}{16}$

with

$K_0 = \max\limits_{0≤c ≤∞}\frac{|χ(c)|^2}{d(c)}$

.

Keywords: Chemotaxis, boundedness, large time behavior, signal-dependent diffusion.
