We consider an elliptic equation with unbounded drift in an exterior domain, and obtain quantitative uniqueness estimates at infinity, ie the non-trivial solution of−△ u+ W⋅∇ u= 0 decays in the form of exp(− C| x| log 2| x|) at infinity provided‖ W‖ L∞(R 2∖ B 1)≲ 1, which is sharp with the help of some counterexamples. These results also generalize the decay theorem by Kenig-Wang [13] or Kenig-Silvestre-Wang [14] in the whole space. As an application, the asymptotic behavior of an incompressible fluid around a bounded obstacle is also considered. Specially for the two-dimensional case, we can improve the decay rate in [16] to exp(− C| x| log 2| x|), where the minimal decaying rate of exp(− C| x| 3 2+) is obtained by Kow-Lin in a recent paper [16] by using appropriate Carleman estimates.
