Final Report Summary - NUMIWING (Numerical modelling of inflatable airborne wind energy systems)
The overall deliverable is an open-source code to model the mutual interactions between airflows and AWE systems. Significant advances have been made on the numerical methods to simulate the complex aerodynamics around kite power wings and its interactions with the structure. At low Reynolds numbers, it has been shown that the flow turbulence around a leading-edge kite wing can impact on the canopy. At high Reynolds numbers, different turbulence models have been tested to accurately model the flow field. Additionally, the immersed-body method used to flexibly simulate fluid-structure interactions has been improved to prevent the flow from entering the structure. This was shown to lead to good results for the purpose of simulating airborne wind energy systems. These new methodologies can now be used to further advance the design and operation of kite power systems.
This research project is frontier both in terms of the technology that is investigated and the numerical models that are developed. Therefore, it impacts at both a scientific level (by developing high-fidelity modelling tools) and a societal level (by investigating novel concepts of renewable energy devices). It also impacts on the career perspectives of the Fellow by bringing together her experience in computational modelling and the host’s expertise in kite power.
