Abstract
We study the equilibrium positions of a long prismatic particle of convex cross-section at a liquid/liquid interface in the gravity-free situation. We show in particular that : i) in a stable equilibrium position the contact angles at both three-phase lines obey the Young equation, ii) for any convex cross-section there are at least four positions for which contact angles obey the Young equation. Moreover, the stability of these positions is investigated.
