NTNU - knowledge for a better world

The Norwegian University of Science and Technology (NTNU) creates knowledge for a better world and solutions that can change everyday life.

Faculty of Engineering Science and TechnologyDepartment of Energy and Process Engineering

A Post-doc position for the project "Boiling of multicomponent mixtures in confined geometries" is available at the Department of Energy and Process Engineering in the Fluid Mechanics research group.

Flow boiling is an efficient heat transfer mechanism often encountered in miniaturized process equipment such as micro- and mini-heat exchangers and micro-reactors. The development of two-phase micro-channel technology requires a thorough understanding of the hydrodynamic and thermal behavior of two-phase flow in such confined geometries. With the introduction of mixture refrigerants as an alternative for the non-environmental friendly refrigerants previously used, the problem of predicting the heat transfer coefficient and heat transfer mechanisms has become more complex.

The focus of this project is on understanding the underlying physical phenomena by means of advanced numerical techniques. The Post-doc candidate will work on the numerical study of bubble dynamics during flow boiling of multicomponent refrigerants inside small diameter channels. The candidate will be responsible for improving and further developing an existing numerical simulation tool based on spectral methods and the diffuse interface approach for describing interface dynamics. For the simulations, special attention will be given to the Taylor bubble flow regime and the dynamics between two consecutive bubbles, and how these affect the heat transfer process. There will be a close cooperation with an already ongoing PhD candidate working under the same project. The candidate will also have a close cooperation with the other students in the group working on similar topics.

The Post-doc position is for a period of 2 years, starting during 2016 if possible. The candidate is expected to hold, or be in the final stages of completing a PhD degree within a relevant discipline. The candidate should demonstrate good background either in fluid mechanics, heat and mass transfer, applied physics or applied mathematical modelling, all with specialization in numerical methods and scientific computing. Programming skills with MATLAB are expected, while basic knowledge of C++ will be considered advantageous for this position. Knowledge in finite element method or spectral methods is required. Experience with parallel computing will be beneficial. General engineering CFD experience based on commercial software will not be sufficient.

Post-doctoral Fellows are normally remunerated at wage level 57 in the State salary scale, gross NOK 483 400 per year (before tax). There will be a 2 % deduction to the Norwegian Public Service Pension Fund from gross wage.
