The goal of this study is to test out the accuracy of the upscaling approach (Jinyu Tang, 2021) for a geothermal doublet. This approach tries to simulate the physical thermal dispersion. When modeling in a geothermal reservoir it would be easy if a lot of layers can be upscaled. However, when doing upscaling one can not just take an average of...

In dit onderzoek is gekeken naar de toepassing van de Scheduled Relaxation Jacobi (SRJ) methode op de tijdsafhankelijke warmtevergelijking. De scheduled Relaxation Jacobi methode is een iteratieve methode die bestaat uit meerdere cycli van verschillende gewichten van iteraties van de gerelaxeerde Jacobi methode. Deze methode is ontworpen om de...

Heat transfer by radiation is something you experience everyday: when walking outside in the sun or when cooking your diner. This thesis provides understandable models of the role that radiation plays in the transfer of heat. By studying literature we developed a mathematical basis for the heat transfer model, where we discuss diffusive,...

In an attempt to find alternatives for solving partial differential equations (PDEs)<br/>with traditional numerical methods, a new field has emerged which incorporates<br/>the residual of a PDE into the loss function of an Artificial Neural Network. This<br/>method is called Physics-Informed Neural Network (PINN). In this thesis, we study dense...

In this paper the research behind the parallelization on the GPU of the time parallel time integration method Parareal. Firstly, the theory behind Parareal and its convergence theorems will be detailed. Then, two test models, the Lorenz system and Heat diffusion equation, will be introduced. Additionally, the derivation of the Forward Euler and...

There are several different methods to solve the steady-state flow problem of district heating networks and gas networks. In this thesis, the nodal method, the loop method, and the loop-node method are compared. This is done in order to determine for what type of network, with specific characteristics, which of these methods is preferred. In...

Welding is an extensively used technology by different industries such as aerospace, automotive and marine industry. Welding involves the temporal melting of materials in order to join them together. The quality of the weld is known to depend on the fluid flow and heat transfer in the material. A way to influence the heat transfer and fluid flow...

The effect of conductive heat transfer recharge originating from the surrounding conduction dominated geothermal system on the geothermal reservoir lifetime has been reviewed during its development, by studying the effect of multiple reservoir and production parameters. A two dimensional (2D) finite volume implicit coupling strategy, using a...

Bluerise has developed a system that uses cold seawater to cool down a fresh water loop. This loop is used for fresh water production. The goal of this study is to improve the overall heat transfer coefficient of the working medium in this system by at least 5%, which will also reduce its size. The overall heat transfer can be improved by adding...

In this thesis, a model for air flow and temperature in urban areas is studied. In particular, the influence of vegetation in a street canyon is investigated. This includes the effect of vegetation on air flow and the cooling property of vegetation to lower temperature in street canyons. Computational Fluid Dynamics simulations with vegetation...

Because the earth loses her heat less efficient, the average global temperature rises. As a result, more extreme weather conditions occur. In urban environments, rain during these extreme weather conditions cannot be discharged immediately. A Polder Roof, a combination of a blue and green roof, provides a solution for this problem. This roof...

Recently, an amount of methane was produced with hot water in the Ammerlaan geothermal field. The presence of methane influences fluid properties and fluid flow in the well, leading to changes in the pressure and temperature drop in the producing well. This study presents a model for non-isothermal two-phase flow in geothermal wells. In this...

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-...

Background Heat waves will occur in Rotterdam with greater frequency in the future. Those affected most will be the elderly – a group that is growing in size. In the light of the Paris heat wave of August 2003 and the one in Rotterdam in July 2006, mortality rates among the elderly in particular are likely to rise in the summer. Method The aim...

For the transition of the built environment towards carbon neutrality, heating with green hydrogen can obtain a key role, especially in countries with a well developed natural gas infrastructure, like the Netherlands. Leading studies show that the existing transport and distribution gas network can be transformed for hydrogen transport at...

Geothermal energy (GE), as an ideal renewable resource for building cooling/heating with stability and abundance in energy supply, has been widely exploited in developing countries. The common utilization forms of GE mainly include the ground source heat pump (GSHP), underground duct system (UDS), and abandoned wells energy (AWE) system....

Energy efficiency measures are a priority in the near term to reduce the carbon intensity of maritime sector in the next years. Since 2017, IMO has been proposing policies to rapidly promote the adoption of cleaner technologies and fuels for oceangoing vessels. Lithium-ion batteries have been recently installed onboard smaller scale ferries...
