PhD Studentship in Chemical Engineering on “Flow of pulp fibre suspensions

Reference number 2009/59
Application deadline 2009-05-15

The project aims at developing a deeper understanding of the flow behaviour of pulp fibre suspensions at concentrations above 3% by weight. At these concentrations, of outmost importance in pulp processing, the suspension shows a complex rheological behaviour. A better understanding of the system could lead to a better utilization of the turbulent energy with reduced energy costs, and /or equipment dimensions, and less fibre damage. Thus, an understanding of the flow behaviour of fibre suspensions is of great interest for the design, scale-up and operation of pulp processing equipment. In particular flow and dewatering effects in the near wall region will be studied in detail, theoretically using mathematical modelling (CFD) and experimentally using PIV, LDA and UVP.

Job description

The project is a joint venture between Metso Paper in Sundsvall, Södra Cell in Värö and Chemical Engineering at Chalmers and is funded by the Swedish National Energy Administration.

The position is limited to maximum five years and corresponds to full-time research studies during four years. In addition, teaching in the undergraduate or masters curriculi at Chalmers could be included corresponding to one year, teaching work distributed over the whole time of the position.

Qualifications

A suitable background is Master of Science in Chemical engineering, Chemical Engineering with Physics, Mechanical Engineering or Engineering Physics; specifically with interest in applied mathematics and transport phenomena.

Application procedure

The application shall be written in English and include the following items:

   1. An application of a maximum of one A4 page containing your specific qualifications for the position
   2. Attested copies of education certificates, including grade reports and other documents
   3. Curriculum Vitae
   4. Letters of recommendation and name of reference persons (optional)

The application shall be sent electronically as pdf or zipped documents. Please use the button at the foot of the page to reach the application form.

If any material is not available electronically or cannot be transferred to pdf format, the material can be sent as a hard copy to Registrar. The applicants name and the reference number (2009/59) must be written on the first page of the application.

PhD Theoretical Chemistry / Chemical Physics (2x2 years)

Within the research Group Theoretical Chemistry of Hasselt University, the following position (m/f) is available:

PhD Theoretical Chemistry / Chemical Physics (2x2 years)
(mandate SBG/2009/001)

Job description
The candidate will prepare a PhD thesis within the framework of a project entitled "From orbital imaging to molecular quantum similarity in momentum space" (financial support by the Fund for scientific Research _ Flanders and the University of Hasselt). The first goal of the project is to develop and apply theoretical methods for quantitative interpretations of advanced “orbital imaging� experiments employing Electron Momentum Spectroscopy (EMS), taking into into account conformational mobility as well as electron correlation and relaxation - EMS is a powerful technique which enables straightforward determinations of orbital momentum densities from an angular analysis of electron-impact ionization & scattering cross-sections. A second aspect of the project pertains to the calculation from these densities of new criteria of molecular similarity, of relevance for the pharmaceutical industry, and of efficient descriptors of the chemical
reactivity, in collaboration with the division of quantum chemistry at the University of Ghent (Prof. P. Bultinck). This proposed research project is a continuation of a PhD thesis that has been awarded by the International Union of Pure and Applied Chemists.

Diploma
Academic license (4 years), master (5 years) of equivalent diploma (bvb. DEA) in chemistry, physics, or materials sciences, or civil engineering in chemistry, physics, or materials sciences. Students who will complete their study this year can also apply.

Offer
Scholarship for a PhD in Theoretical Chemistry / Chemical Physics within the research group of Michael S. Deleuze (awards by the World Association of Theoretically Oriented Chemists and by the Royal Flemisch Academy of Belgium for Sciences and Arts). The scholarship is available for a period of 4 years. It consists of a first appointment of 2 years, followed by a prolongation of 2 years unless negative evaluation of the first period. The scholarship is subject to social security. Important computer facilities and a supporting research environment are available for the candidate (for more information on our research activities, visit our website: http://www.uhasselt .be/theochem).
