Turbine Design & Performance

The first objective of this research theme is to assist in the selection of expanders for optimum performance, for the application given. Selection algorithms will be derived from the development of performance models for 3 candidate expander configurations. The models are used in the design process to evaluate design options and their performance in relation to the cost of plant. The results of the research and algorithm development will be implemented into the AGGAT EDT.

Second objective is to build turbo machinery design expertise by establishing an advanced modelling and design technique for turbo-machinery which includes preliminary and detail design capability, plus sophisticated analyses of flow and stress behaviours. Designers will receive guidance to ensure they focus on performance, durability, and low-cost manufacturability. Design expertise in turbo-machinery design will be built by establishing an advanced modelling and design technique of turbo-machinery which includes preliminary and detailing design capability, plus sophisticated analyses of flow and stress behaviours. Designers will be guided to focus on performance, durability, and low-cost manufacturability.

The selected expanders and turbines of at least 2 different designs each will be investigated for their thermodynamic performance, power output, wear and corrosion under experimental conditions differing according to the operating requirements of the 5 chosen binary fluids. The evaluated performances will be compared against software models developed for expanders/turbines. Pilot scale versions of the expanders/turbines to 250kW will be constructed for performance evaluation. Renowned turbine design experts and the dedicated AGGAT industry design teams will be involved in the design, construction and scale up aspects of this research theme of honing their own design and manufacturing capabilities.

Expander Technology Research

Under this technology research objective, a pre-selected set of expanders and turbine designs is created, analysed and simulated for performance characteristics. Using state of the art modelling software, 3-D models of turbines will be created to be implemented into potential turbine design models for use after construction in testing facilities. The expanders and turbines are optimised for dimensions and thermodynamic performance under virtual environments which will be the basis for development of turbine products for different applications. This work is being carried forward under the guidance of Dr. Susan Krumdieck and key AGGAT researchers.

Turbo-machinery Technology Development

With international collaboration as support for this part of the AGGAT programme, turbine models accessed from overseas are tested in AGGAT testing facilities for their performance whilst simultaneously compared with models developed under virtual environments. The focus of this objective is to test real turbines in real operating environments whilst also analysing their behaviour in the context of virtual models and their simulation results. This study is expected to provide the underlying knowledge, know-how and experience to ultimately create new turbine concepts and designs for implementation as innovative power generation technology products. The progress in this project is being ensured by Dr. Dirk Pons through close collaboration with expander research in the earlier mentioned project.
