Abstract
The thesis provides the study of a 30P30N wing profile at a high Reynolds (1.7M) and the effects of an active flow control device on its performance. Two different angles of attack will be studied: AOA = 5.5⁰ for the validation process and AOA = 14⁰ for the synthetic jet actuator study. The purpose of the project is to study the performance of the high-lift configuration wing using a Large-Eddy-Simulation turbulence modelling and the effects of the actuator on the lift, drag and the overall efficiency. It has been seen that the mesh has a huge impact on the LES simulations as turbulence phenomena is difficult to predict and requires a lot of computational resources. Under the specific configurations of the synthetic jet actuator used, there is no clear improvement on the performance of the wing even though minor benefits or little differences between the angle of the exhaust velocity can be identified. The memory of the project is differentiated in different chapters. In Chap. 1, all the info about the organization of the project is written. In Chap. 2, you can find all the information about the theoretical basis of the project. Then, Chap. 3 includes the cases studied to validate the meshing, turbulence modelling, etc. Chap. 4 is the object of study of this project, where the reader can find the actuator configuration and the effects of the actuator on the wing’s overall performance. Finally Chap. 5, where the conclusions of the project and future steps will be explained.
