Sprays are routinely used in the food, chemical, pharmaceutical and medical, transport and energy industries. They are commonly, used for example, in cooling applications, surface processing and coating, transport (e.g. fuel injection) and the production of powdered materials., This project will be centred upon droplet distribution, droplet generation and breakup near a spray nozzle. The droplet distribution, in turn, is required to evaluate the effect of droplets on the carrier gas (velocity and temperature), vapour concentration, distribution and size of deposits.
The aim of this project is to deliver an insight into droplet generation and droplet distribution by their sizes and velocities. The aim will be met via (i) design of the experiments on a flat fan water spray; (ii) process the statistical data and images obtained from the experiments. It is planned to combine two complementary techniques, namely, high-speed planar imaging and processing and pointwise, PDA measurements, to obtain time-resolved, droplet size and velocity distributions. The investigation will include the coarse atomisation process in the near nozzle region using the high-speed imaging as well as the distribution of fine, dispersed droplets, further from the nozzle using the PDA. The project is experimental but will include important modelling elements; it constitutes an element of the ‘Next generation spray simulation model (NGSSM)’ project funded by the UKRI.
The successful applicant will become a member of a larger group working on the project, which includes theoretical and experimental studies and will work in close collaboration with all members of the team. The team will be based within the University of Brighton’s Advanced Engineering Centre.
The Advanced Engineering Centre (AEC) is an internationally-acclaimed Centre of Research Excellence, focused on developing new knowledge to address long-term applied thermofluids challenges. The AEC has built a world-leading reputation for its research team in advanced physical and mathematical models for fuel sprays. The Centre is renowned for its specialised optical and laser-based measurement techniques applied to state-of-the-art optical research engines. The successful applicant will have access to these unique facilities and expertise.
For this PhD project, we welcome applicants with an enthusiasm for experimentation, computer simulation and programming, and with the ability to work both independently and as part of a group.
