Aeroacoustic modeling of a LOX/CH4 rocket engine for high-frequency combustion instability prediction analyses

High-frequency combustion instabilities represent the main technical risk faced by design engineers when developing new chemical rocket propulsion systems. Such instabilities are driven by the coupling between the flames’ heat release rate and the combustion chamber’s acoustic field. As such, they can only be assessed during detailed design...

Simulation of the Dutch electricity system: A software expansion for the Illuminator

The aim of this report is to discuss the design of the software that creates a simulation for the national electricity grid level of the Netherlands. This is done by further developing the open-source energy system integration development kit called the Illuminator. Where the goal of this software is to create an extra case, add a Graphical User...

Supply Chain Simulation of Offshore Wind Farm Monopile Installation: Performance of different supply chain configurations under dynamic weather influences

A monopile installation project consists of the whole process of loading monopiles to vessels, transporting monopiles to the wind farm and drilling monopiles in the seabed. Each installation project has different characteristics as the weather at the installation location, the distances to the suppliers and the vessels that are available differ...

Wargame Simulation: Exploiting the Power of a Flow-Based Design

Military decision-making involves art and science and aims to translate strategic goals into tactical actions for achieving specific outcomes. It relies on a commander’s capacity to navigate complex and sometimes ambiguous situations to develop detailed plans and actionable orders. At the military tactical level, decisions focus on executing...

Urban Livability Research and a Pollution Emission Case Study in Delft

At present, many studies have begun to focus on evaluating urban accessibility and livability, which can be a series of great guidance for future urban planning considering residents’ personal perceptions of various living aspects. It can be observed from the existing literature that urban accessibility has a mature evaluation system,...

Waiting and rebalancing strategies in an urban waterborne transport environment

This thesis explores waiting and rebalancing strategies in urban waterborne transport, intending to improve the efficiency and operational performance of water transportation systems. The study is based on a review of the literature on waterborne transport and waiting and rebalancing strategies. This is followed by a case study where the found...

Analysis of the impact of traffic density on training of reinforcement learning based conflict resolution methods for drones

Conventional Air Traffic Control is still predominantly being done by human Air Traffic Controllers, however, as the traffic density increases, the workload of the controllers increases as well. Especially for the area of unmanned aviation, driven by the rise in drones, having human controllers might become unfeasible. One of the methods that...

Dimensions of data sparseness and their effect on supply chain visibility

Supply chain visibility concerns the ability to track parts, components, or products in transit from supplier to customer. The data that organizations can obtain to establish or improve supply chain visibility is often sparse. This paper presents a classification of the dimensions of data sparseness and quantitatively explores the impact of...
