Etude numérique et expérimentale de l'écoulement autour d'un rotor éolien [PDF]
, 2013 An improved model of an actuator surface is proposed, representing the flow around a wind turbine. This model was developed in conjunction with a Navier-Stokes solver using a blade element method for the calculation of power and wake development.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
Chemie Ingenieur Technik, EarlyView.A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Multidisciplinary optimization of an axial turbine
IOP Conference Series: Earth and Environmental ScienceAbstract The results of three different optimization setups for an axial propeller turbine consisting of a guide vane, a runner and a draft tube are presented. The first setup only contains the efficiency as objective and the design head as a constraint. In the second setup, the minimization of the cavitation volume is added as a further
