TitleCavitation damage through non-axisymmetric self-focusing
CategoryPhD Studentship
EmployerQueen Mary University of London
LocationUnited Kingdom, London
InternationalYes, international applications are welcome
Closure DateThursday, February 29, 2024
Cavitation is responsible for material damage in nature and a large number of engineering applications. Recent experimental evidence suggests that a hitherto unknown shockwave-focusing non-axisymmetric mechanism might be primarily responsible for erosive cavitation [Reuter et al., Ultrason. Sonochem., 90, 106131 (2022)]. In particular, for a range of small bubble to wall distances, the collapse of the bubble has been found to occur progressively, while being continuously self- amplified by the shockwaves emitted during this process. The small characteristic scales of the collapse mean that experiments can only provide limited insight into the flow, whereas performing non-intrusive measurements is another major challenge. The goal of this project is to investigate the emergence, sensitivity, and significance of the self-focusing mechanism in erosive cavitation. The project will utilize large-scale state-of-the-art CFD simulations of single and multiple bubble configurations near solid surfaces to advance our understanding of the processes leading to cavitation damage and explore potential pathways for its mitigation.


This studentship arrangement covers home tuition fees and provides an annual stipend for up to three years (currently set at the 2023/24 stipend rate of £20,622 pa).

Note that Queen Mary Research Studentships cover home-rated tuition fees only. Overseas applicants would be required to meet the difference between home and international tuition fees.


The minimum requirement for this studentship opportunity is a good honors degree (minimum 2(i) honors or equivalent) or MSc/MRes in a relevant discipline. If English is not your first language, you will require a valid English certificate equivalent to IELTS 6.5+ overall with a minimum score of 6.0 in Writing and 5.5 in all sections (Reading, Listening, Speaking). Candidates are expected to start in September (Semester 1).
