The growing demand for air travel and concerns about its environmental impact demands urgent action. The scientific community has acted by fixing milestones to be achieved within 2015-2025: a reduction of 75% in NOx emission and the improvement of 70% in efficiency in terms of Specific Fuel Consumption (SFC).
Turbine rotor disks are one of the most highly stressed components in the modern aero-engine. The hot flow in the turbine annulus is characterised by strong unsteadiness, and there is the risk of damaging the disks blade due the leakage of hot streams inside cavities through the seals. An effective way to control the temperature in blade disks is to purge cold flow inside the cavities. This constitutes what is generally known as secondary air system. Both academic and industrial worlds are currently investigating fundamental mechanisms involved in such systems.
The proposed project will be developed within the Turbomachinery Research Centre (TRC) at University of Bath, which is a leading group in the investigation of secondary air systems. The centre is worldwide known for the development of theoretical models and experimental facilities for the investigation of the flow in rotating cavities in turbines.
The project involves the development and improvement of the state of the art CFD techniques (LES-DES) starting on the basis of a well-established and validated unstructured CFD in-house solver available at University of Bath. CFD approaches such as U-RANS simulations have been the workhorse tool to design a wide range of components in turbomachinery, but have demonstrated clear limitations in catching the structures governing the flow inside the cavities. The successful candidate will aim to identify the role of the large scale flow structures in cavities and will provide the key for a better understanding of the results collected in the experiments carried out at TRC.
The successful applicant will work in a friendly and multi-disciplinary environment. The work will be carried out in close collaboration with industrial partners such as Siemens and Safran.
