Asymptotic study of Leray solution of 3D-Navier-Stokes equations with exponential damping

Abstract We study the uniqueness, the continuity in L 2 {L}^{2} , and the large time decay for the Leray solutions of the 3D incompressible Navier-Stokes equations with the nonlinear exponential damping term a ( e b ∣ u ∣ 2 − 1 ) u a\left({e}^{b| u{| }^{{\bf{2}}}}-1)u , ( a , b > 0 a,b\gt 0 ).
