The condition, often caused by a lack of surfactant in the underdeveloped lungs of prematurely born babies, can lead to blocked airways causing severe breathing difficulties. To reopen a blocked airway a pressurised finger of air has to be forced deep into the airway.
Dr Matthias Heil and Dr Andrew Hazel, of the University’s School of Mathematics have created the first 3D computer simulation that mimics the complex process by which a propagating air finger reopens the collapsed airway. This process involves a complex interaction between fluid mechanics, the air pressure, surface tension and wall elasticity inside the airways.
Dr Heil said: “When the lung collapses you want to be able to reopen airways as quickly as possible but you do not want to damage the lung. There is a very fine balance between the amount of pressure you can apply and the potential damage you might cause.
“Currently this assessment has to be made by a medic solely based on experience. We hope that our simulation will help to inform and improve the medical treatment of infants and adults suffering from this condition.”
In their paper, ‘Finite-Reynolds-Number Effects in Steady, Three Dimensional Airway Reopening,’ Heil and Hazel demonstrate the importance of ‘fluid inertia’ when assessing the pressure required to reopen a blocked airway.
They find that if ‘fluid inertia’ is not taken into account the estimated pressure required to reopen a blocked airway is too low. In addition, they find that the reopening pressure decreases as the level of airway collapse increases.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
