Would you like to use your fluid dynamics skills and experience to make an 
impact on paediatric heart disease?

Almost 1% of babies are born with a congenital heart defect (CHD) and of 
these between 10 and 20 % develop pediatric heart failure. These infants 
need a new heart, but due to the shortage of donor hearts, not enough 
transplants can be performed. Working with an international team of 
researchers from Texas Heart Institute, Gunma University and Griffith 
University, within the NeoVAD project funded by the US NIH, we will design 
the world's smallest ventricular assist device, a pump to help babies' 
failing hearts. Your role will be to use CFD to design the flow path. Using 
either ANSYS or OpenFoam, in combination with machine learning algorithms, 
you will optimise the geometrical design. It will be important to consider 
both the hydrodynamic characteristics (including pressure head and 
efficiency), the potential blood trauma (including haemolysis) and the 
growth of infants from babies to children.

Applicants will have a PhD in biomedical, mechanical, aeronautical or 
chemical engineering, or other relevant field of engineering, physical 
sciences or applied maths. The successful Research Associate will have:

A strong background in fluid dynamics and CFD experience.
High level analytical ability.
Ability to program, including for example: Fluent UDFs, OpenFoam solvers, 
and Matlab, Python or similar.
A track record of conducting high quality research, evidenced by 
publications in peer reviewed journals.
Excellent communication and organisation skills, enabling effective working 
in an international, multidisciplinary team.
The ability to work independently.
Expertise in machine learning, and knowledge of turbomachinery, and 
haemodynamics in cardiovascular devices, is desirable but not essential.
The initial fixed term contract is 6 months, starting 1st March 2021 or as 
soon as possible after. The project will finish 30th June 2024 with NIH 
funding renewed annually. Due to Covid19, this role will be a mixture of 
remote working (within the UK) and working on campus when required, subject 
to change in line with government guidance. The normal working place is the 
University of Bath. Collaboration with the project partners will be 
predominantly electronic, with travel funding for extended international 
visits, and conferences. There will be opportunities to supervise Masters 
project students

This is a chance to join a growing team of cardiovascular mechanics 
researchers within the Department of Mechanical Engineering. Projects within 
the group range from fundamental studies of how blood flows, through to the 
design of new cardiovascular devices, and encompass both experimental and 
numerical research methods. This project is led by Dr Katharine Fraser and 
the successful applicant will join her group, while also benefitting from 
membership of the Centre for Therapeutic Innovation (CTI). CTI is a 
University-wide community of academics, researchers and research students 
working on innovating therapies from discovery through diagnostics to 
treatments.

For informal enquires please contact Dr Katharine Fraser via email 
khf27@bath.ac.uk

Our campus is surrounded by beautiful countryside, and the City of Bath with 
its historic charm and social activity only a short distance away creates an 
excellent environment in which to work.

The University of Luxembourg within its multi-disciplinary and -cultural 
environment seeks a post-doc collaborator for participating in an advanced grant 
at the interface of academia and industry. The objective is to investigate and 
model macroscopic concrete flow behaviour with regard to both, the influence of 
the interface layer at the wall and the particle interactions, being the key 
issues for fundamental modelling of concrete rheology. Therefore, the aim of the 
present project is the investigation and modelling of time- and shear-dependent 
microstructure (disperse properties) and rheological properties of cementitious 
suspensions subjected to shear applying the Immersed Boundary Method (IBM). In 
this project, the addressed key issues are 
    • shear induced particle migration (SIPM), 
    • interface layer and its formation mechanisms, 
    • local shear rates induced by larger particles and its effect on 
microstructure and rheology taking chemical and physical based particle-particle 
inter-actions into account. 
Only a scale-bridging approach from the micro-scale (dparticle<100 μm) over the 
meso-scale (0.1≤dparticle≤4 mm) to the macro-scale (dparticle>4 mm) enables to 
adequately address these issues and herewith achieve the goal to model and 
predict the flow behaviour. Here, suspensions relevant to the construction 
industry, i.e. cement paste and concrete containing super-plasticizer, are 
considered in this project. 

The Grand Duchy of Luxembourg, in the heart of Europe, a multilingual country,
