Behavior of HAWT with Differential Planetary Gearbox
Journal of Power and Energy Engineering, 2014 A dynamic model for simulating behavior of a horizontal axis wind turbine (HAWT) with differential planetary gearbox is developed. The aerodynamic load applied to the wind turbine connected with the carrier is described using the quasi-steady approach. The control torque is assumed to be applied to the external ring of the gearbox.

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,
