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,

Procedure Selecting Pumps Running as Turbines in Micro Hydro Plants
Energy Procedia, 2017 Abstract The authors present a combined method using statistical and numerical models for selecting a pump running as turbine in micro hydro plants. The data of the site (head and capacity) allow calculating two coefficients, C Q and C H , which identify the pump to use successfully as turbine in that place.
