Two-dimensional flows of foam: drag exerted on circular obstacles and dissipation
, 2004 A Stokes experiment for foams is proposed. It consists in a two-dimensional flow of a foam, confined between a water subphase and a top plate, around a fixed circular obstacle. We present systematic measurements of the drag exerted by the flowing foam on
