Dimension reduction for compressible Navier–Stokes equations with density-dependent viscosity
Abstract In this paper, we investigate the Navier–Stokes equations describing the motion of a compressible viscous fluid confined to a thin domain Ω ε = I ε × ( 0 , 1 ) $\varOmega _{\varepsilon }=I_{\varepsilon }\times (0, 1)$ , I ε = ( 0 , ε ) ⊂ R $I_{ \varepsilon }=(0, \varepsilon )\subset \mathbb...
