Minimizing the climate impact of the next generation aircraft using novel climate functions for aircraft design

The aircraft’s environmental performance on fleet level is so far completely decoupled from the design process. The climate impact from aviation arising from non-CO2 effects are largely independent from CO2 emissions, but rather depend on the atmospheric state. Previously complex climate-chemistry models were used to evaluate the non-CO2...

An Efficient Modeling Approach for Probabilistic Assessments of Present-Day and Future Fluvial Flooding

Risk-informed flood risk management requires a comprehensive and quantitative risk assessment, which often demands multiple (thousands of) river and flood model simulations. Performing such a large number of model simulations is a challenge, especially for large, complex river systems (e.g., Mekong) due to the associated computational and...

Robust map building for robot navigation in dynamic environments

Simultaneous Localisation and Mapping (SLAM) provide a novel solution for the robots to localise and navigate an unknown environment. Initial SLAM research focused mainly on the indoor environment, assuming the background to be primarily static. In contrast, the real world has dynamic interactions that restrict the implementation of SLAM to...

Instant flood risk modelling (Inform) tool for co-design of flood risk management strategies with stakeholders in Can Tho city, Vietnam

Flood risk reduction strategies play an important role in flood risk management (FRM) and these strategies are being co-designed with the engagement of the stakeholder through multiple consultations and co-designing sessions. Effective participation of stakeholders in interactive work sessions requires fast and accurate modeling systems with...

How to efficiently design aircraft with minimum climate impact?

Given the comparably high impact of aircraft emissions, especially their non-CO2 effects, on climate in the order of 5%, aviation stakeholders are required to act to reduce the warming effects of air traffic. Besides new operational procedures, like e.g. climate-optimized routing, this demands the development of completely new global-warming...

Flexibility in adaptation planning: When, where and how to include flexibility for increasing urban flood resilience

The magnitude and urgency of the need to adapt to climate change is such that addressing it has been taken up by the United Nations as one of the sustainable development goals - Goal 13 (SDG13) in 2015. SDG13 emphasises the need to strengthen resilience and adaptive capacity to climate related hazards and natural disasters. Coping with urban...

A comparison between numerical predictions and experimental results for horizontal core-annular flow with a turbulent annulus

An experimental and numerical study has been made of oil-water core-annular flow in a horizontal pipe with special attention for the turbulence in the water. An experimental set-up was built to be able to compare numerical predictions with detailed experimental results. The oil density was considerably smaller than the water density. Full 3D and...

The Effects of Viscosity on Core-Annular Flow: Numerical Simulations and Experiments for Core-Annular Flow

A study has been performed on the effects of the viscosity of the liquid in the core of core annular flow. This is a multiphase flow regime for two immiscible liquids in a pipe where the high-viscosity liquid forms a core and the other low-viscosity liquid forms a lubricating annulus around the core and along the wall. This is a very efficient...

Passive Filter Design and Optimisation of Harmonic Mitigation in Wind Power Plants

Over exploitation of fossil fuels and ill effect of global warming have forced human civilisation in search of new sustainable energy resources. Renewable energy resources like hydro, solar, wind , biomass etc., are environmental friendly energy resources. One such renewable energy resource is Wind Energy. The growth of offshore wind farms is...

Application of ultrasound to remove thrombi from the Left ventricular assist device

Due to limited number of donor hearts and stringent eligibility criteria for heart transplant the Left ventricular assist device (LVAD) has emerged as a relevant treatment option for heart failure. Occlusion in the form of a thrombus (blood clot) is a feared complication associated with the LVAD. The ability of ultrasound to result in effects...

Machine Movement Prediction for Collision Avoidance

Construction sites are among the most dangerous work environments. Worldwide, thousands of workers are injured or killed while working with or around machinery. For Volvo Construction Equipment, safety of the workers is one of the core values. The company strives for the vision of "Zero accidents with Volvo Group Products " through high quality...

The axect flow behind a yawed conical shock

The College of Aeronautics was founded in 1946 and was granted university status in 1969 becoming the Cranfield Institute of Technology. In 1993 it changed its name to Cranfield University.
