Urban Drone Operation: How wind in cities could affect air taxis of the future

Written by

Dr Abdulghani Mohamed studies gusts encountered by flying vehicles such as drones or air taxis in proximity to buildings.

In cities, many companies are now considering urban air mobility vehicles, from drones for parcel delivery to air taxis for travel. However, gusts of air, especially around buildings, can create pockets of wind with different properties, which could cause areas of turbulence and affect the stability of the aircraft. A research team led by Dr Abdulghani Mohamed, senior lecturer at […]

Cascading energy: Explaining fluctuations in the solar wind

Written by

An image of the sun emitting rays of energy, and the Earth's magnetic fields dispersing the energy. Dr Charles Smith has explored fluctuations in solar wind, using the latest theory of fluid dynamics to understand how dissipation of energy might provide better explanations than previously used Alfven wave models.

Originating from the dynamic upper reaches of the Sun’s atmosphere, the influence of solar wind can be felt throughout the solar system. We sat down with Dr Charles Smith at the University of New Hampshire to discuss how the latest theories of fluid dynamics, combined with observations from spacecraft missions, can help us to understand turbulence in the interplanetary plasma.

Molecular hopping in solid-like liquids: Understanding the self-diffusion and viscosity of liquid molecules

Written by

To fully understand how liquids flow, it is crucial for researchers to build models which can accurately recreate their behaviours on molecular scales – yet since the time of Newton, the complexities involved have presented numerous challenges. In their research, Prof Russ Keanini, Prof Peter Tkacik and Prof Jerry Dahlberg at the University of North Carolina, Charlotte, present new ways […]

Modelling sea-island reversal in viscoelastic phase separation

Written by

In the 1990s, researchers first discovered that within mixtures of viscoelastic materials, unique transitions known as phase separations can appear when the right conditions are applied. In his research, Mr Yoshihide Kubo, Hiroshima University alumnus, presents the first robust approach for modelling these systems, avoiding unnecessary complexities while producing results which can be easily reproduced in experiments. His work addresses […]
