CARE-3 Cavity acoustics and Rossiter modes

Purpose and goal:

The purpose of this project is to complete the doctoral studies that began in 2020. Two previous project with partial funding from Vinnova have contained experimental studies supported by numerical analyses. This is around cavity resonances combined with shear layer instabilities. The concrete goals for CARE-3 are two additional journal articles and a doctoral thesis as well as a completion of the experimental database regarding boundary layer variations.

Expected results and effects:

This project contributes to building competence in the field by methodically developing an experimental database of generic configurations intended as numerical validation data for the development of industry calculation tools. This leads to a better prediction ability and increased competitive advantages for the Swedish aviation industry. Participating industry partners and academia act on a global market, providing opportunities for further positioning of companies and academia in international contexts.

Approach and implementation:

The project starts 2024-09-01 and ends 2025-05-31. It contains three work packages, one of which is project management of the industry and the second a measurement campaign regarding the incoming boundary layer and the third which is publications and a thesis. The main focus of academia is to complete the PhD studies in a coherent manner and the main focus of industry is to supplement the numerical calculation tools with complementary test data.
