Underground thermal energy storage (UTES) is an efficient technique to fulfill the heating and cooling demand of buildings. UTES uses stable subsurface temperatures store and extract energy. This study covers two types of UTES systems: aquifer thermal energy systems (ATES) and borehole heat exchangers (BHE). UTES systems in the Netherlands have...

In a future scenario, the successful development of geothermal industry will result in the large-scale deployment of new deep geothermal projects. In highly populated areas, such as the Netherlands, such a development will lead to a dense grid of neighbouring licenses. In such a situation a new project requires careful design and planning as the...

An experimental investigation was done regarding the propulsion system and airframe integration issues associated with the novel Flying V configuration. The experimental investigations involved a series of wind tunnel tests with a 4.6% scale half model, conducted in the TU Delft OJF low speed wind tunnel. Balance measurements allowed significant...

The main objective of this study is to quantify interference effects between production and injection wells for geothermal projects that operate within the same reservoir. The secondary objective is to study the time it takes for the reservoir unit to thermally recharge after production has stopped. Two reservoir simulators are benchmarked to...

With the increase in the number of radar systems/radio applications, FMCW radars currently face various interference problems which lead to wider noise band, rise in noise floor level and masking of weak targets. This thesis aims to eliminate different types of interference for FMCW radars.<br/>In this thesis, we propose a interference...

The safety in the high voltage substations rely on the integrity of its grounding grid. A single discontinuity at any part of the grounding grid may cause a swell in touch or step potential that may expose the personnel to a hazard of critical electric shock. It may also lead to malfunction of the protection devices leading to erroneous tripping...

The Flying-V is a novel flying wing concept where the main lifting surface has been fully integrated with the passenger cabin. Previous studies have focused on the aerodynamic and structural design of the airframe; but, prior to determining which engine-airframe integration alternative is most beneficial (e.g. boundary layer ingestion, distributed...

Building Integrated Photovoltaics (BIPV) has the potential to play a major role in the ongoing transition towards nearly zero energy buildings. However, the BIPV market is still a niche market, representing only 1% of the global PV share. One of the main barriers that hinder the deployment of BIPV is the lack of aesthetic flexibility. Architects...

Automotive radars play a very important role in reduction of traffic accidents and casualties by making the vehicle fully self aware of its surroundings. For the vehicle to be fully self aware multiple sensors or radars have to placed in close proximity of each other on the body of the automobile. This will lead to interference between the...

Automotive radars play a crucial role in the reduction of traffic casualties and the realization of autonomous driving due to its robustness and adverse weather tolerance. However, as the penetration rate of automotive radars increases, concerns arise regarding the mutual interference. In contrast to the predominant Frequency-Modulated...

Automotive radar is a key element in Advanced Driver Assistance Systems (ADAS). With the growth of Automotive industry, there is a high demand for the sensors used in assisting systems. As the number of sensors increases, probability that these systems being in close proximity will also increase. This will lead to situations where in multiple...

The energy system is a complex socio-technical system, characterised by a multitude of stakeholders, different goals, long-term investments, and large scale sub systems with long lifetimes. The government of the Netherlands aims to support the transition of the energy system of the Netherlands towards a sustainable system by implementing policy...

Experimental techniques to measure rotorcraft aerodynamic performance are widely used. However, most of them are either unable to capture interference effects from bodies, or require an extremely large computational budget. The objective of the present research is to develop an XV-15 Tilt Rotor Research Aircraft rotor model for investigation of...

During this last half year this thesis was executed in order to obtain a clear and scientific underpinned exploration of what interferences in an office environment are and how they can be reduced. As a result of combining the performed literature study, internal analysis, and external analysis a new product proposal is developed: the Bay A...

Boundary Layer Ingestion is an integrated propulsion concept in which a propulsor operates in boundary layer flow instead of the free streamflow with the goal to reduce the fuel flow for a given operating condition. The objective of this thesis is to obtain a better understanding of the power benefit of an installed pusher propeller at the aft...

WLAN 802.11 (WiFi) and WPAN 802.15 (Bluetooth) operate in the same 2.4GHz ISM band. OFDM WLANs are designed to provide very high data rates, resilience to multipath and extended operating range. One of the main barriers to actually achieving the high data rates is the interference from the Bluetooth systems which is one of the main sources of...

To accommodate the growing demand for wireless communications, new techniques are required to increase throughput of wireless networks. One technology aiming to increase the spectral efficiency of wireless devices is full duplex (FD) radios. These systems are capable of single carrier transmission and reception and could ideally double the...

Wireless sensor and actuator networks (WSANs) suffer from interference making them unfeasible for actuators that require reliability. This asks for an IEEE 802.15.4 behavior analysis for building automation actuators and a robust WSAN solution. This thesis uses the IEEE 802.15.4 based JenNet communication stack for experiments to define, measure...

Wireless Body Area Network (WBAN) is used for communication among sensor nodes operating on, in or around the human body in order to monitor vital body parameters and movements. A typical sensor node in WBAN should ensure accurate sensing of the signal from the body, carry out low-level processing of the sensor signal, and wirelessly transmit...
