PhD Studentship in Fluid Dynamics-purifying air in ventilated rooms & buildings

The subject of this studentship is the study of the fluid mechanics of air purification in ventilated rooms. The aim is to develop a clear understanding of the links between the rate of air purification, the location and operating conditions of the purifying device, its orientation within the room and the geometry of the room.

The motivation for this research stems from compelling evidence that the number of people suffering from allergies that are triggered by airborne impurities in rooms is on the rise. These allergies, with symptoms common to asthma, can be triggered by exposure to a spectrum of allergens found in the indoor environment, such as pollen, mould spores, dust mites, or irritants in the air, such as pollution, smoke, odours or chemical fumes. By 2050 asthma is expected to represent the most prevalent chronic childhood disease and result in one of the highest causes of health care costs.

The research will involve a combination of experimental work in our new Fluid Dynamics Research Laboratory and complementary theoretical modelling. The project offers the candidate the opportunity to address both fundamental and applied questions relating to air purification, and buoyancy-driven and forced airflows in rooms. For further details contact Prof. G.R.Hunt:

Applicants should hold, or expect to be awarded, a good degree in Engineering, Physics, or Mathematics.

The studentship covers full tuition fees at the UK/EU rate and offers a 3.5 year tax-free stipend at the rate of £17,553 p.a. Details can be found at

Applications should be submitted via the University of Cambridge Graduate Admissions web pages naming Professor G.R.Hunt as the proposed Supervisor
