Purpose and goal
The objective of the project has been to study a turning vane heat transfer, with influence of an upstream turbine and different operating conditions (on-, off-design), and to use the measurements to validate CFD methods. The project objective is in general fulfilled, and can be summarized: a)Influence of upstream turbine unsteadiness is less than expected b)Influence of off-design conditions is larger than expected c)CFD predicts the heat transfer fairly well, and can be used as a tool to calculate the vane heat transfer.
Expected results and effects
The project results will be used in future development project, med goal to predict more accurate temperatures and life. The goal is to reduce time for development and cost for expensive engine testing. The developed measuring techniques can be used in future projects and rigs.
Planned approach and implementation
Projektet genomfördes som ett lyckat samarbete mellan Chalmers och Oxford University. En gemensam doktorand tillbringade tid på både Chalmers, Oxford och GKN. Olika turbinriggar och riktiga motorprov användes för att mäta värmeövergång, med olika mätteknik. CFD metoder har använts för att jämföra olika mätresultat med varandra. Kontakter har skapats inför framtida samarbeten och projekt.
