## Abstract In this paper we prove unique solvability of the generalized Stokes resolvent equations in an infinite layer Ξ©~0~ = β^__n__ β1^ Γ (β1, 1), __n__ β₯ 2, in __L^q^__ βSobolev spaces, 1 < __q__ < β, with slip boundary condition of on the βupper boundaryβ βΞ©^+^~0~ = β^__n__ β1^ Γ {1} and nonβ
In simulations of propagating blast waves the effects of artificial reflections at open boundaries can seriously degrade the accuracy of the computations. In this paper, a boundary condition based on a local approximation by a plane traveling wave is presented. The method yields small artificial ref
