Wind load simulations and inertia scaling using an industrial robot arm

Existing wind load simulators such as wind tunnels and fans have multiple disadvantages, especially when used in a scaled-down environment. This paper proposes to simulate wind loads by using an admittance-controlled industrial robot arm rigidly attached to a research object. Admittance control should make it possible to simulate wind loads and...

Modelling, simulation and analysis of green gas injection into the gas distribution network

The increase of the average world temperature, as a result of greenhouse gasses, is one of the greatest challenges the world is currently facing and will be facing in the future. One of the many efforts to reduce the increase of carbon dioxide, is to decarbonize the gas network by replacing natural gas with renewable gasses like green gas. Since...

Thermal Exposure in Concrete Tunnels Subjected to Fire

<br/>To date, many fire accidents have occurred in tunnels all over the world. In the worst cases, there were catastrophic consequences with numerous human casualties and significant economic impacts. In the occurrence of such tunnel fires, besides the primary concern of saving human life, ensuring a certain level of structural integrity is also...

Validation of Dynamic Power System Models using Synchrophasor Measurements

A dynamic power system model cannot perfectly predict the behaviour of a physical power system. Model validation tries to answer the question whether the model predicts the behaviour of the physical system sufficiently. This study evaluates if and how a dynamic power system model of the Dutch power grid can be validated using PMU measurements....

Dynamic simulation of a geothermal reservoir: Case study of the Dinantian carbonates in the Californië geothermal wells, Limburg, NL

In the context of the energy transition, rapid development of the geothermal sector in the Netherlands has to take place. The first steps have been taken by establishing the Green Deal UDG between multiple industrial consortia, which agree to share knowledge on the research and use of ultra-deep geothermal energy . The Dinantian carbonates are...

Modelling Regional Power Grids for Large-Disturbance Stability Studies

Due to the shift in electrical energy generation from thermal synchronous generators towards various renewable sources, power system stability will become a more pressing issue in the near future. In this thesis, we explore possible improvements to the dynamic grid model currently used by TenneT TSO for large-disturbance stability studies,...

Molecular Dynamics Simulation on Mechanical behavior of Si Nano Cantilever under Ar Bombarding

In nano world, it is cheap and repeatable to make 2-dimensional structures, such as nanoholes and thin nanofilms. However, it is expensive to build 3-dimensional structure in a repeatable manner. Ion bombard- ment is a technique which is widely applied in engineering areas, such as thin film deposition, etching, and analysis. In this thesis work...

Predicting the diffusivity of CO2 in substituted amines

The experimental determination of the diffusivity of carbon dioxide (CO2) in an amine solvent is difficult as the CO2 diffuses and reacts simultaneously when absorbed into an amine solvent. As the knowledge of the diffusivity and solubility of CO2 is essential to design the absorption units based on amine solvents, the nitrous oxide (N2O)...
