Pumping when the wind blows: Demand response in the Dutch delta

This thesis investigates the potential of a large pumping station in IJmuiden, the Nether-lands, for participating in Demand Response. Due to climate change, renewable energy is onthe rise. The intermittency of energy, together with its unpredictable supply, are a big hurdlefor the energy transition. Two methods are promising solutions to this...

Wet compression with a twin screw compressor prototype

The main objective of this study was to develop a quick model for an oil free twin screw compressor. The computational time of the model was to be kept as low as possible so that the model could be used for quick estimations and optimizations of the process. This was done by using a simple geometry focusing on the volume curve and port sizes,...

Sediment transport modelling: Determination of the main areas contributing to the suspended sediment load in the Mara River, Kenya

The Mara River originates in Kenya in the Mau Escarpment and flows through the Serengeti ecosystem into Lake Victoria in Tanzania; in total it is about 395 km long. In this river, human interventions have led to increased of agricultural areas. As a result, increased fast runoff and top soil erosion is expected. Consequently, more sediments is...

Estimatino of the water-gas-ratios of gas wells offshore by a data-driven model

During gas production offshore, also water is produced. There are gas numbers available per well, but the water production is only known for several wells together. This thesis tries to model the water production per well based on the available data. This is done through a least-squares method. The report shows that it is very difficult to find...
