本文研究了粘性可压缩导热毛细流体在自由面区域内的运动。证明了在各向异性Sobolev-Slobodetskii空间中描述这种运动的问题的解的局部存在唯一性。该解使得速度和温度属于W2 +α,1 +α/2 2(Ω ×(0,T)),密度属于W1 +α,1/2+α/2 2(Ω ×(0,T)),Ω <$R3,α ∈ [3/4,1].
In the paper the motion of a viscous compressible heat conducting capillary fluid in a domain bounded by a free surface is considered. We prove the local existence and uniqueness of a solution to a problem describing such a motion in anisotropic Sobolev–Slobodetskii spaces. This solution is such that the velocity and temperature belong to W 2+α,1+α/2 2 (Ω × (0, T )), and density to W 1+α,1/2+α/2 2 (Ω × (0, T )), Ω ⊂ R3, α ∈ [3/4, 1).
