PhD position in modeling of fluid particle coalescence

A PhD position is available at the Department of Chemical Engineering, NTNU for research work within the Environmental Engineering and Reactor Technology group. The position is devoted to the modeling of fluid particle coalescence. The appointment has a duration of 3 years with the possibility of until 1 year extension with 25% teaching duties in agreement with the department. The position is financed by the Research Council of Norway and has a special responsibility for the project “A Multidisciplinary Approach to Characterize Coalescence in Petroemulsions”.

 

Information about the Department
The current research fields at the Department includes biorefinery and fiber technology, catalysis, colloid and polymer chemistry, environmental engineering and reactor technology and process systems engineering. Information about the department is available on the Departments homepage: http://www.ntnu.edu/chemeng. Further information is available at: https://www.ntnu.edu/chemeng


Job description
Fluid particle coalescence is taking place in many industrial multiphase process units and in nature. Improved understanding of the fluid particle coalescence phenomena is required in order to develop models and optimize the design and performance of such process units. 
      

This research project consist of three work packages. We will use a) experiments, b) molecular dynamics simulation, and c) macroscopic film drainage models, to describe the film drainage and interphase rupture mechanisms in the coalescence processes. The PhD candidate employed in this position will be responsible for the theoretical task in work package c) deriving so-called jump conditions (a kind of boundary conditions) connecting the dispersed phase fluid and the continuous phase fluid at the interfaces from first principles for viscous and non-Newtonian interfaces. This theoretical work involves differential geometry, rheology and tensor analysis. Based on the resulting jump conditions, the candidate will employ lubrication theory (thin film analysis) to describe the film drainage and/or instantaneous coalescence phenomena in emulsions. The effects of interface rheology on the film drainage and rupture phenomena will be investigated at the level of individual emulsion droplets in stagnant fluids. The model framework may be extended to turbulent flows.

 

In the remaining two work packages the researchers in the project will provide necessary information required for the application of the film drainage model to relevant systems.

 

In this position it is possible to have a short research period abroad at our collaborating universities.

 

Detailed information on our PhD programs is found at: http://www.ntnu.edu/nt/research/phd

 

Qualifications
The applicant must have an MSc (or equivalent) in chemical engineering, fluid mechanics, physics, nanotechnology, mathematics or related disciplines, and a documented background in modeling, model implementation and theory relevant for this project. Experience in modeling work including differential geometry and tensor analysis is considered an advantage.


The successful candidate should be creative, independent with a strong ability to work problem oriented. He/she should also enjoy interdisciplinary research and take keen interest in learning and working in teams.

 

The regulations for PhD programs at NTNU state that the applicant must have a master degree or equivalent with at least 5 years of studies and an average grade of A or B within a scale of A-E for passing grades (A best). Candidates from universities outside Norway are kindly requested to send a Diploma Supplement or a similar document, which describes in detail the study and grade system and the rights for further studies associated with the obtained degree: http://ec.europa.eu/education/tools/diploma-supplement_en.htm

 

The position requires spoken and written fluency in the English language.

 

Terms of employment
The appointment of the PhD fellows will be made according to Norwegian guidelines for universities and university colleges and to the general regulations regarding university employees. Applicants must agree to participate in organized doctoral study programs within the period of the appointment and have to be qualified for the PhD-study. 

 

NTNU’s personnel policy objective is that the staff must reflect the composition of the population to the greatest possible extent.

 

The position as PhD is remunerated according to the Norwegian State salary scale. There is a 2% deduction for superannuation contribution.
