Simmes, Wout (author)As the world population is increasing and cities grow faster than before, food scarcity becomes a bigger issue. To depend less on import and decrease CO2 footprint, food should be produced nearby its consumers. A good solution for food production is a greenhouse which provides a steady high yield throughout the year. Some of the world's fastest...master thesis 2021

Bergstein, Pieter (author)To answer the need for renewable fuels, Zero Emission Fuels is designing a microplant to create methanol from carbon dioxide and water from the ambient air using only renewable energy from solar panels. For this microplant, gaseous carbon dioxide must be compressed from 1 to 50 [bar] with the low mass flow of 336.7 [g/h]. This thesis examines...master thesis 2021

Hovenga, Nick (author)In order to reach the goals of the Paris Agreement, global emissions must decrease at a high rate. Looking at the industrial sector, the largest share of energy is used for process heating, with fossil fuels as its primary source. A way to improve the energy efficiency and reduce the emissions of process heating is by the integration of heat...master thesis 2021

van der Stoel, Dave (author)In the report that is before you, a method has been investigated to increase the capacity of domestic hot water tanks. To do so without having to increase the volume of the tank, a phase change material has been included in an annular space around the tank. To test the performance of such a system, three main topics are dealt with in this report...master thesis 2020

Heere, Daniel (author)The vehicle industry is increasingly exploring emission-free mobility. Transforming the mobility sector to zero-emission vehicles that consume renewable and low carbon fuels is necessary to reduce the impacts on climate change. Hydrogen powered electric vehicles, or Fuel Cell Electric Vehicles (FCEVs), could make a significant contribution to...master thesis 2019

Zijm, Peter (author)Heatpipes are promising devices for geothermal energy extraction owing to their<br/>effectiveness to transport heat. The goal of this research is to validate an analytical heatpipe model with experiments and to investigate the difficulties in designing and constructing geothermal heatpipes. There is a lack of literature and research concerning...master thesis 2019

Carels, Ivo (author)Zero Emission Fuels B.V. develops a standalone System that produces renewable methanol from air and sunlight. In this thesis the steady-state model of this System is replaced with a Simulation Tool that can predict its behaviour for every minute of a year. The goal is to verify how technical design parameters influence methanol production and to...master thesis 2018

Schoenmaker, Lars (author)In this thesis diffuser performance will be simulated with computational fluid dynamics, which will be done with the program Ansys Fluent. The expanding geometry creates an adverse pressure gradient and under certain conditions there will also be separation.<br/><br/>At first a relative simple simulation will be done of a one-directional...master thesis 2017

Van den Baar, M.L.R. (author)Sustainable supply of heat for space heating and domestic hot water heating has received increasing interest in Europe. Assessing the performance of a building heating system with energy analysis has limitations regarding the implementation of sustainable heat, because energy analysis only takes into account the quantity of energy. Exergy...master thesis 2016

Postma, T.M. (author)A solar powered micro gas turbine is a new technique which is currently under development. Although promising, a turbocharger as replacement for a micro gas turbine could provide a simple, compact and low cost alternative. Therefore this research focusses on the energetic and technical performance expectations of a turbocharger based solar micro...master thesis 2016

Kalaiyarasan, K. (author)Large scale deployment of renewable energy for production of electricity have led to impact on the electricity scenario of many countries. Because of the seasonality of newly added power sources electricity infrastructure has to be flexible enough to feed in with additional power in case of deficit and consume more in case of surplus. This leads...master thesis 2016

Berthold, C.R. (author)In this work a numerical method is developed to efficiently simulate limit cycle oscillations and forced response amplitudes of fluid-structure interaction (FSI) problems. The method computes a solution in the frequency-domain and can therefore only deal with periodic unsteadiness. As flow solver the Harmonic Balance method is used which is...master thesis 2016

De Jong, B.A. (author)Broadband turbulent noise can lead to fluid-acoustic and fluid-structure interaction and ultimately to mechanical failure of pipe systems. In HVAC (Heating Ventilating and Air Conditioning) systems broadband turbulent noise can radiate outwards where it is a nuisance or even harmful to people. A fast and simple approach for investigating...master thesis 2016

Van den Berg, A.H.W.F. (author), Verkooijen, A.H.M. (author)Large-scale coal-fired power plants are typically designed as base-load units. This means that they are traditionally run at continuous high loading levels, most often full-load. The current energy market asks for more flexibility as renewable energy sources continue to penetrate the energy market. Coal-fired power plants are forced to operate...master thesis 2015

Jacobs, J.G.B. (author)In this study a thermoacoustic single stage engine configuration is compared to a double stage engine configuration with regard to onset temperature, power density and efficiency. A thermoacoustic prime mover was designed and build using air at 1 atmosphere as a working fluid. The ceramic regenerators were heated using electricity and cooled...master thesis 2014

Groot, S. (author)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...master thesis 2014

Hermans, C.W.M. (author)In this research a new rotary chemical looping combustion (CLC) reactor was developed which is suitable for larger scales and solves some of the issues of both fluidized bed and fixed bed configurations. It should therefore be able to produce a continuous hot gas flow, in order to make it compatible with large-scale energy or heat production.To...master thesis 2013

Michas, D. (author)The desalination industry has grown exponentially the last four decades as countries seek solutions to water scarcity caused by population growth, climate change, pollution and industrial development. All source water types included, reverse osmosis is the prevalent desalination process, accounting for more than half of the global capacity. The...master thesis 2013

Van Eckeveld, A. (author)Enhanced greenhouse gas emisions in the past century contributed to the global average temperature rise. The emission of greenhouse gases, therefore, should be limited in the coming decades. One way to do so is by capturing the greenhouse gasses (like CO2) from industrial flue gases (post-combustion capture). This can be achieved in a chemical...master thesis 2013

Van Vliet, E.H.A. (author)Plans have been made to change the current district heating grid at the TU Delft to a smart thermal grid. New heat suppliers will be connected to the grid including a geothermal well and waste heat from the Schie area. The heating grid will change from a demand driven grid to a combination of demand and supply driven heating grid. Demand side...master thesis 2013
