The aviation industry is shouting out its aim to reach ”net-zero carbon” by 2050. Nevertheless, air traffic is expected to grow up until then, and if fuel consumption is reduced by new technologies and aircraft, other sources of global<br/>warming such as N Ox emissions and contrails are less considered. Therefore, the climate impact improvement...

This thesis focuses on simulating the refuelling process for a liquid hydrogen-powered commercial aircraft. The liquid hydrogen is intended to flow from the refuelling truck, through a transfer line, into the aircraft’s tank using pressure feed. The numerical simulation was built upon an existing tank model, however it did not consider the...

The validity of current prediction methods for the formation of contrails from modern turbofan engines is investigated. A modelling framework has been developed for estimating the impact of engine configurations on contrail formation by analyzing the physics of the mixing between core and bypass flow. Within this framework, Engine Performance...

Progressing targets on GHG emission reduction urge the the Netherlands Ministry of Defense (NL MoD) to reduce the use of fossil fuels, as they announced to contribute to the Paris agreement by reducing its dependency on fossil fuels by at least 70% by the year 2050. However, without sacrificing striking power, because future naval combatants...

This report covers all major steps to establish an aviation emission inventory for 2019. This emission inventory is set up based on four consecutive steps. The first step is to gather all required data in the information model and this also includes some pre-processing of data to make it as complete as possible. The second step is to estimate...

This work describes the benefits of exploiting cold hydrogen in a 2 MW liquid hydrogen-electric powertrain. Hydrogen is stored in a liquid state in the aircraft at its boiling point of 20 K (at 1 bar). Fuel cells require an input temperature of at least zero degrees Celsius to operate. The heating process can either be done by drawing current...

In this thesis, a modelling approach to model soot emissions for a Rich Burn-Quick Quench- Lean Burn (RQL) type aero engine combustion chamber will be presented. The sot emissions will be modelled by coupling Chemical Reactor Network (CRN) approach with Method of Moments with Interpolative Closure (MOMIC), a detailed soot formation model. The...

This thesis covers the experimental characterisation of a multi-nozzle research combustor capable of achieving flameless combustion (FC). The combustor is operated with methane as fuel and air as the oxidiser, under an overall lean equivalence ratio ranging from 0.6-0.9. The work focused on designing and applying different experimental...

An accurate estimation of gas turbine nozzle guide vane metal temperature locally on its surface is crucial for predicting vane lifetime. The stagnation region at the vane leading edge is, typically, exposed to the highest thermal load, thus, the showerhead configuration of film cooling is often applied on the leading edge. Widely used lean-...

To reduce emissions from civil aviation, research is being conducted in lean premixed hydrogen combustors as part of the APPU project at the TU Delft. Next to mitigating CO2 emissions completely, these technologies have the potential to also reduce NOx emissions greatly, allowing for the future of civil aviation to become sustainable. However,...

To further advance combustion technology, this thesis analyzes a counter swirler setup and its ability to enhance properties such as shear for droplet breakdown or recirculation. The purpose of this project is to perform a cold flow analysis of a dual axial swirl combustion chamber, with axial air injection. The main aim of the thesis is to...

Boundary layer ingestion is a concept that can reduce the power requirement of an aircraft. The ingestion of the boundary layer creates non-uniform fan inflow conditions. This thesis work aims to research the effect of installation in a propulsive fuselage concept on fan performance. On top of this, the effect of fan installation on the...

In the last few years, there has been a growing awareness regarding the climate impact of aviation in the general public. With global warming effects becoming more severe, it is important that aviation drastically reduce its emission footprint to keep the impact on the climate lower. There have been ongoing efforts by various organizations such...

Swirl-stabilised hydrogen combustion has great potential in the aviation industry since emissions can be significantly reduced compared to fossil fuels. However, a major drawback is a high proneness to flashback. This could be overcome with non-swirling axial air injection (AAI) on the centre-line of the mixing tube. The effect of this concept...
