The project will be part of a wider programme of research with activity ranging from advanced material characterisation and processing to fluid flow analysis. The broad area is the development of novel materials using micro and nano material processing.
This particular 4 year PhD research will aim to develop a methodology for the combined experimental and computational characterisation of cavitation in centrifugal pumps. The aim is to help interpret the impact of micro and nano textures applied to the surface of the pump impeller on the wear induced by cavitation. The primary focus of the research will be the experimental study but the aim is to leverage computational simulations to complement experimental observations. The successful candidate will be expected to develop a purpose built closed-loop test rig. Measurements will rely on phase locked high speed imaging. The main components of the test facility will include a VFD controlled motor connected to a pump impeller via a torque-meter. The impeller will be encased in a transparent volute to facilitate visual access to the cavitation. The computational part of the research will rely on existing computational solutions developed at the partner institution, the FluidDyn laboratory at ENSAM ParisTech. The computational methods have been previously validated and will be applied to characterise cavitation induced stresses around micro-textures.
