TERA- A Tool for Aero-engine Modelling and Management [PDF]
, 2007 One of the distinguishing features of the civil aero-engine market is its high competitiveness. The costs and risks associated with new projects are such that the difference between two apparently equally attractive options could result in success from

Multiobjective gas turbine engine controller design using genetic algorithms
, 1996 This paper describes the use of multiobjective genetic algorithms (MOGAs) in the design of a multivariable control system for a gas turbine engine. The mechanisms employed to facilitate multiobjective search with the genetic algorithm are described with ...

Business Strategy and the Environment, EarlyView.ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

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,

Potential Analysis of On‐Site Oxygen and Ozone Production for Wastewater Treatment Plants
Chemie Ingenieur Technik, EarlyView.The potential of a power‐to‐gas process focusing on the oxygen stream to cover an upcoming demand of ozone at German wastewater treatment plants is analyzed. Economic and ecological parameters are compared to the conventional production of hydrogen and oxygen. Powered by on‐site produced wind energy, the process is deemed beneficial.

Chemie Ingenieur Technik, EarlyView.All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...
