Netherlands: PhD Position in Boiling Flow-Regime Maps at University of Twente

Font size: Decrease font Enlarge font
In this project, two PhD students and a post-doc will study flow-pattern development in heated ducts under boiling conditions. One of the PhD students, stationed in Eindhoven, will carry out experiments with two different fluids, in two test rigs, with advanced measuring techniques such as phosphoric LIF, while the second PhD student, stationed in Twente, will focus on numerical modeling and simulation of flow-pattern development under phase transition.   In the Multiscale Modeling and Simulation group research is conducted on mathematical models, analysis and simulation strategies for fluid mechanical problems. The theme relevant for the topic of boiling flow regimes is phase-transitional flow. Particular attention in this project will go to transport processes across interfaces between vapor bubbles and liquid as occurring during flow regime transitions in heated two-phase flows.   The diffuse interface model will be further developed to allow simulation of such flows with boiling in ducts. The connection with the experimental work will be sought to strengthen the validation of the model and facilitate scaling of the flow-regime maps measured.   The PhD student in this computational modeling project will contribute to the research objectives through:   • development of new simulation capabilities in multiphase fluid dynamics for simulation of boiling phenomena; • implementation of numerical methods on High Performance Computing facilities; • application of the developed simulation tools to a range of realistic regimes of boiling heat and mass transfer

This computational research project requires an MSc in applied mathematics, physics or engineering with interest in scientific computing, physical modeling and numerical methods. We are looking for a talented researcher with an active attitude, an accurate way of working, and excellent communicative and collaborative skills. Experience in high‐level programming languages (Fortan 90, C++) together with decent knowledge of Linux operational systems are welcomed. Practical knowledge of parallel programming with Message Passing Interface (MPI) will be an advantage. Drive, initiative and self-reliance are important qualities as well.   Your application should consist of • A cover letter, emphasizing your specific interest, qualifications and motivation to apply for this position • A full Curriculum Vitae, including a list of all courses and grades obtained • A short description of your MSc research • Contact information of two references that may be consulted   Starting date by arrangement no later than December 2013.

The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which drives change, innovation and progress in society. The University of Twente is the only campus university in the Netherlands; divided over six faculties we provide more than fifty educational programmes. The University of Twente has a strong focus on personal development and talented researchers are given scope for carrying out pioneering research. The faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) comprises three disciplines that shape Information and Communication Technology. ICT is more than communication. In almost every product we use mathematics, electronics and computer technology and ICT now contributes to all of societies’ activities. The faculty works together intensively with industrial partners and researchers in the Netherlands and abroad and conducts extensive research for external commissioning parties and funders. The research which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research institutes MESA+, CTIT and MIRA.
