Modelling and Design Guidelines for Ram Air Ducts Using the Meredith Effect

Applied to an Organic Rankine Cycle Waste Heat Recovery System

With climate change posing increasing risks, the Advisory Council for Aviation Research and Innovation in Europe (ACARE) aims to reduce CO2 emissions by 75% and NOx emissions by 90% per passenger kilometer by 2050, compared to a baseline aircraft from 2000. The ARENA project addr ...

Exploration of a Reverse Turbo-Brayton Cryocooler for Carbon Neutral Aeronautical Applications

Integrated Cryocooler Design and Tank Modeling for Cryogenic Liquid Hydrogen in Long Range Flight

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 resea ...
The rise in temperature attributed to human CO2 emissions and the escalating energy needs of society necessitates the development of clean energy production. Solar and wind energy, both renewable sources, have emerged as cost-effective alternatives to conventional fossil fuel sys ...
This study analyses the feasibility of an engine architecture using bypass cooled cooling air as a method for reducing specific fuel consumption of current and future high bypass turbofan engines. As cooled cooling air reduces required turbine cooling massflow, a major source of ...

Techno-Economic feasibility analysis of Solid-Oxide Fuel Cell-Gas Turbine based hybrid propulsion system fueled by Hydrogen

How a Solid-Oxide Fuel Cell can impact the performance of the propulsion system and the economics of the aircraft

The world is moving towards sustainability and there is immense pressure on Aerospace Industry to reduce its emissions to contribute to a carbon-neutral world. However, maturing gas turbine technology is a big bottleneck towards this goal and hence, this project focuses on the te ...

Dynamic Modelling of a Solid Oxide Fuel Cell System

Integration of 1-D SOFC Dynamic Model with the Balance of Plant components

The constant pressure on the maritime sector to reduce Greenhouse Gas (GHG) emissions has led the shipping industry to search for alternatives, such as zero-emissions propulsion systems, which would allow meeting the 2050 target imposed by International Maritime Organization (IMO ...

Organic Rankine Cycle (ORC) Power Plants can be of greatimportance in the energy transition as they are suitable for converting wasteheat to power and can utilize renewable energy for their operation. To improvethe efficiency of ORC Power Plants, the physi ...
