Climate change is a pressing issue. Hydrogen aircraft are an excellent alternative to current kerosene aircraft, and appear to be the most viable long-term solution for net-zero flight. One of the main challenges for hydrogen aircraft is to sustain a low boil-off rate. This research explores the solution of active cooling of the LH2 mixture in...

In the scope of global decarbonisation, hydrogen has been identified as an essential energy carrier. Not only as an energy storage solution for further electrification in vehicles but also as a primary fuel source in processes that rely on chemical energy which cannot be easily electrified. However, at ambient conditions, hydrogen is also a very...

Propeller propulsion systems combined with Boundary layer ingestion (BLI) have been proposed as a propulsive system to reduce the CO2 emissions of aircraft by 50% by 2050. BLI leads to increased disturbances at the propeller disk and causes more noise due to the fluctuating blade loading. Using the APPU project as a test case, unsteady inflow is...

The use of CFD-based optimizations is becoming a standard for turbomachinery design. Although the use of such optimizations can lead to great improvements of the machine performances, there are still several shortcomings in the common design procedure of turbomachines. In fact, this entails the optimization of the component shape, and only a...

Vello, Riccardo (author)
The objective of this thesis was to further the validation effort on the SU2 flow solver for non-ideal compressible flows. To do so, an uncertainty quantification infrastructure based on the V&V20 validation standard was developed. To determine whether a model error was present, the different sources of uncertainty were combined and then...

Dawn Aerospace is developing a small launch vehicle in the form of a spaceplane, which is powered by a turbopump driven rocket. To reach higher engine efficiency and save weight, there is a need for a small highly-power dense turbine. The efficiency of small turbines strongly depends on the tip gap sizes compared to the blade height. Existing...

As aircraft manufacturers push for better fuel economy, novel aircraft concepts, like the propulsive fuselage concept have emerged. One of the prime component of such concepts is the boundary layer ingestion (BLI) engine. Such engine operates by ingesting the low-momentum fluid emerging from the surface of the aircraft fuselage which enables to...
