Title
(EN) DEVICE FOR ACTIVE CONTROL OF THE READHESION OF A FLOW ON A PROFILE
(FR) DISPOSITIF DE CONTRÔLE ACTIF DU RECOLLEMENT D'UN ÉCOULEMENT SUR UN PROFIL
Abstract
(EN)
A device for penetrating into a fluid, comprising at least one profile (10), a fluid injector (14), a means for measuring the separation of the flow (18) along the profile, downstream of the injector, and an injector activity controller (12) designed to: - store measurements y(t) over time t of the flow separation measurement means, - send, and store instructions u(t)= 0 or 1 over time t of inactivity or activity respectively of the injector, - calculate a quantity σ(t) dependent on quantities y(t), u(t), and on various received parameters, then compare same to a parameter σ* depending on the received parameters and a target value of the flow separation measurement means, and then deduce an activation or deactivation of the injector.
