Unsteady Boundary Layer Transition Measurements with Infrared Thermography: Development of Improved Measurement Schemes

The boundary layer transition location is a crucial design parameter in aerodynamics. The computational prediction of boundary layer transition in engineering applications is typically based on empirical models. These models require experimental measurements for calibration and validation purposes. For unsteady aerodynamic processes, the range...

Designing the End-of-Use Consumer Experience in a Circular Economy for the Apple iPhone

The aim of this project was to design an end-of-use experience in a circular economy for the Apple iPhone. The main challenge was to find out what the obstacles were at the end-of-use. During this research it became clear that many consumers don’t do anything with their old phone when they buy a new one. These old iPhones are left forgotten in...
