Toussaint, M.A. (author)
The polytropic model to describe air expansion, has been used for years to describe the behavior of surge vessels. In this thesis the alternative to describe this behavior, the Rational Heat Transfer (RHT) equation developed by Graze (1968), is extended with an estimation of all heat terms in surge vessels. The RHT model is compared to the poly-...

Modern Computer Aided Design/Engineering can assist in the design of highly optimized engineering structures. Such structures allow for a significant reduction on the strain of resources across the product life cycle, where the potential for weight reduction is most beneficial for the aerospace industry. However, their production is currently...

The parameterization of heat transfer by remote sensing, and based on SEBS scheme for turbulent heat fluxes retrieval, already proved to be very convenient for estimating evapotranspiration (ET) over homogeneous land surfaces. However, the use of such a method over heterogeneous landscapes (e.g. semi-arid regions or agricultural land) becomes...

The work presents the measured heat capacity of the (Li1?xCax)F1+x liquid solution. Four samples with different compositions have been prepared and measured using a Differential Scanning Calorimeter. Since this technique was newly adopted for measuring encapsulated fluoride samples, some modifications were introduced in the standard...

There are millions of lakes and ten thousands of reservoirs in the world. The number of reservoirs is still increasing through the construction of large dams to meet the growing demand for water resources, hydroelectricity and economic development. Accurate information on the water balance components of lakes and reservoirs is deemed necessary...

The local material expansion and contraction involved in welding result in permanent deformations or instability i.e., welding distortion. Considerable efforts have been made in controlling welding distortion prior to, during or after welding. Thermal Tensioning (TT) describes a group of in-situ methods to control welding distortion. In these...

Solid-State Lighting (SSL), powered by Light-Emitting Diodes (LEDs), is an energy-efficient technology for lighting systems. In contrast to incandescent lights which obtain high efficiency at high temperatures, the highest efficiency of LEDs is reached at low temperatures. The thermal management in LED product is then a key design parameter as...

Today is a turning point for the energy system in European cities. Shall the exploitation of fi-nite resources continue, or is another path possible, not only technically but also economically? Efforts to curb energy consumption and greenhouse gases emissions have so far been centered on electricity in the European Union, not on heat. Untapped...

In this report a district heating system is analyzed at the Tata steel site. A case study is made for a number of buildings, which are currently heated with a gas boiler. A computer model is developed to calculate the optimal piping path and diameters for such a network. The heat losses of this network are calculated with the complex potential...

As indoor sports shoes are intensively used in a warm and sweaty environment for periods of up to three consecutive hours, the built-up heat inside is insufficiently released causing warm and perspiring feet. This results in an increased chance of blisters and skin irritations. Experimental research on the ventilation properties of the shoe was...

The merging of building and landscape through the design of a smart sound barrier with integrated functions. The project is located in Utrecht and is dealing with the problems of insufficient housing, disappearing green areas, lack of connection between the city and its surroundings, and sound pollution caused by the A12 highway. In essence the...

A fully glazed facade is a facade which provides maximal advantages for buildings concerning daylight and view. Daylight reduces the energy use for lighting; view provides comfort and gives the possibility to experience the surroundings of the building. The possibility of providing solar entrance into the building has big influence on the...

This thesis looks into the possibility to produce geothermal energy in the Roer Valley Graben. The locations in this area are limited due to the low permeability of the deep Triassic layers. Fractures can enhance the heat production by increasing the effective permeability and decrease the pressure that is needed to produce the heat. However,...

In this thesis the technical and economic performance of compression-resorption heat pumps has been investigated. The main objective of this thesis was to improve the performance and reduce the investment costs of compression-resorption heat pumps applied in process industry. A model that is able to capture the performance of most heat pumps...

Sustainable design faces challenges at a scale and level of complexity that are ill at ease with design’s mainstream focus on products and users. Recently, social practice theory has been suggested as a promising theoretical framework to inform new ways of designing. In social practice theory, practices – socially shared entities such as...

Transmission electron microscopy (TEM) has been well known as a powerful characterisation tool to understand the structure and composition of various materials down to the atomic level. Over the years, several TEM studies have been carried out to understand the compositional, structural and morphological changes a material undergoes as a...

The aim of this thesis is to investigate whether other representation techniques of the in-cylinder pressure signal, besides the current pressure-crank angle curve, have the potential of improving the diagnosis in a condition monitoring program. Investigated are the quantitative representation of the heat release through Vibe parameters and the...

Heating constitutes about 40% of the final energy consumption at TU Delft. In the present, the district heating system in campus obtains its energy from the combustion of natural gas in a combined heat and power plant. Although this plant produces heat and electricity with an efficiency over 80%, the dependance on a fossil fuel presents an...

This report describes the development of energy storage strategies for short term Thermal Energy Storage in residential buildings with an air-source heat pump. Short term TES allows advanced integration of renewables because the associated mismatch between demand and availability is solved. The aim of the research was to develop control...
