Berlin Open Depot: Public Art Depot for Germany

The Berlin Open Depot complements the cultural heart of Kulturforum, the cultural center of Berlin, located on Potsdamer Straße in the Berlin-Tiergarten district, situated on one of the busiest transportation nodes of Berlin. It is a center for a wide range of exhibition types and stands among the global frontrunners in the field of innovative...

The Old Harbour: The Next Step in the Housing Career of Modern Elderly

The number of elderly citizens in the Netherlands is growing, but there is a lack of suitable housing for this population group. Because of this, they occupy larger homes that are more suitable for families with children. Since the average age of no longer having children at home is 55 years in the Netherlands, that is the starting age for this...

Design of a needle control device for MRI-guided interventions

This graduation project consists of the design of the needle control device for MRI-guided interventions. It is an apparatus that grabs and steers a flexible needle remotely, so it could be used in an MRI while the physician controls the needle based on the scans. In this way, the physician has a clear sight of the position of the needle and the...

Hydro-elasticity of a Bulge Wave Energy Converter in the 2D Frank Close-Fit Method

Hydro-elasticity is important in the evaluation of a category of wave energy converters (WEC). In this paper, the hydro-elastic response of a bulge wave energy converter is examined by the implementation of a two-dimensional potential theory. The numerical implementation of the Frank Close-Fit method (FCFM) defines hydrodynamic coefficients and...

Airfoil Optimization for vertical axis wind turbines

This thesis addresses the process of airfoil optimization for vertical axis wind turbines (VAWT). The airfoils are designed for large scale turbines above 5 MW. The VAWT concept is relevant for offshore floating wind energy, because of its low center of gravity (stability) and their simplicity (low maintenance). An optimal tip speed ratio of 4-4...

The evolution of sandbars along the Colorado River downstream of the Glen Canyon Dam

The Colorado River in the Grand Canyon area has a lot of sandbars but they are eroding. Since the building of the Glen Canyon Dam and the Hoover Dam in the 1960s, sediment is trapped in the upstream lake. The inflow of water is clear, cold and nearly sediment free. The only noticeable remaining inflow of sediment in the Colorado River is by two...

Fieldwork Coastal Engineering, Redesigning Cape Sirius, Varna, Bulgaria

This report is written for the course ‘Fieldwork Hydraulic Engineering’ held between the TU Delft and Sofia University. The course consisted of 19 participants who carried out measurements in and around the small village St Konstantin, near the Bulgarian city Varna, from the 29th of September till 6th of October. The report describes the results...

Droplet size and velocity measurements in annular flow using phase-Doppler anemometry

The two-phase flow patterns in a wet gas well production pipe are annular flow and churn flow. This research studied the droplet characteristics and entrained liquid fraction as the annular flow pattern changes to churn flow. Measurements have been performed in a vertical flow rig with 50 mm tube diameter using air and water as the two phases....
