The proposed research is focused on predicting and controlling deformation and flow of a group of complex materials abundant in nature and industry, called Yield-Stress (YS) or viscoplastic (VP) materials. These start to flow when a sufficient stress is applied to them but behave as solids otherwise.
DEADLINE: 22nd January 2021
Predicting the behaviour of YS materials is particularly challenging for at least three reasons:
(a) It is challenging to determine material properties accurately.
(b) Inappropriate constitutive models have often been used, i.e.,
generalized Newtonian fluid models, whereas recent experiments have
shown that they also exhibit elastic and thixotropic properties.
(c) It is challenging to compute complex flows because of their transient nature.
In response to the challenge of predicting flows of YS materials,
it is imperative to establish a coherent and efficient approach to
predict such flows by (a) developing more accurate and general YS
constitutive models, (b) developing advanced numerical methods for
computing complex YS flows In this way, it will become possible to
bridge the gap between science and modelling developed in academia
(fluid mechanics, rheology, and computational methods) and process
engineering (food, chemical, pharmaceutical, oil exploration,
The overall goal of our research effort is to develop such models and test them in homogeneous and specific complex and practical flows.
What is funded 3 Fellowships
Duration 4 years
In the selection process, candidates will be assessed upon the following skills:
- Ability to analyze and model complex physical problems
- Programming skills (good knowledge of at least a language among Fortran 2015, C++, Python, Matlab)
- Background in soft matter, multiphase flows, and transport phenomena
- Enthusiasm about working in a multidisciplinary, collaborative environment.
- Excellent interpersonal and communication skills (written and spoken English)
- Ability to work and collaborate in a diverse environment.
- Can be of any nationality, and there is no age limit.
- At the time of recruitment, they must be in the first four years of
their research careers and not yet have been awarded a doctoral degree.
The four years start to count from the date when a researcher obtained
the degree which would formally entitle him/her to embark on a
- Researchers are required to undertake
transnational mobility (i.e., move from one country to another) when
taking up their appointment. One general rule applies to the appointment
of researchers: At the time of recruitment by the host beneficiary,
researchers must not have resided or carried out their main activity
(work, studies, etc.) in the country of their host beneficiary for more
than 12 months in the three years immediately prior to the reference
date. Note that the mobility rule applies to the
beneficiary where the researcher is recruited and not to beneficiaries
to which the researcher is sent or seconded.
- For all recruitment,
the eligibility and mobility of the researcher will be determined at
the time of their (first) recruitment in the project.
