Abstract
We analyze the behavior of weak solutions to compressible viscous fluid flows in a bounded domain in
\({{\,\mathrm{{\mathbb {R}}}\,}}^3\)
, randomly perforated by tiny balls with random size. Assuming the radii of the balls scale like
\(\varepsilon ^\alpha \)
,
\(\alpha > 3\)
, with
\(\varepsilon \)
denoting the average distance between the balls, the problem homogenize to the same limiting equation. Our main contribution is a construction of the Bogovskiĭ operator, uniformly in
\(\varepsilon \)
, without any assumptions on the minimal distance between the balls.
