Sweden : Doctoral student in Combustion Engines oriented towards Waste Heat Recovery

Doctoral student in Combustion Engines oriented towards Waste Heat Recovery

The Division of Combustion Engines works with next generation engines with less environmental impact. To actively do something about the global emissions of CO2 and other green house gases we need to find a more fuel efficient engine for our vehicles but at the same time we cannot allow local emissions to increase. Div. of Combustion Engines are world leading in the fields of HCCI and the subsequent PPC engine technology. To this highly dynamic research group we are currently looking for four Ph.D. students

Work
Waste Heat Recovery. This project is a joint effort with Chalmers, KTH and Lund University and focuses on further increasing the fuel efficiency of combustion engines by utilizing the waste heat expelled from the exhaust system and if possible other losses. Chalmers is focusing on a Rankine cycle attached to the exhaust system and KTH is working with turbo compounding. The task of the student in Lund is twofold. The first task is to provide the students in Göteborg and Stockholm with input data on available exhaust energy for conventional engine operation as well as high fuel efficiency PPC combustion. The second task is to evaluate the HAM concept. HAM stands for Humid Air Motor and is a concept patented by Lund researchers in the 1990:s. and since then installed in a number of ship engines. With HAM, water is transformed to steam between the turbo compressor and engine using coolant energy. The humid air is then fed to the engine where the added water vapor can reduce NOx emissions by 70-90%. Finally the added mass flow through the engine can be used to extract more energy from the turbo expander. With the same concept for gas turbines, EvGT, power can be doubled and fuel efficiency increased 50-70%. Investigating how much improvement can be achieved with the concept using combustion engines is the task for the Ph.D. student. The project is funded by the Swedish Energy Administration and will have a reference group with industry members.

Eligibility
Employment as a Doctoral student can only be granted if you have been accepted to the postgraduate student program. Acceptance to the postgraduate student program is based on the estimated ability to perform well in your postgraduate studies. This is also one of the basic criteria for employment. Furthermore you need a valid university degree at advanced level (MSc) within a relevant study program.

Qualifications
A suitable background for this position is M.Sc. (Civilingenjör) or equivalent with some documented knowledge in thermodynamics and/or engine processes. Mechanical engineering, Engineering Physics or Chemical Engineering would be suitable. We especially welcome female applicants.

Selection criteria
Selection to postgraduate studies is based on estimated ability to perform well in the studies. The evaluation of the ability to perform well is based primarily on the results of the studies on basic and advanced level, in particular:
1. Knowledge and skills relevant to postgraduate studies within this area, such as course work in aerosol physics, meteorology, and environmental science. This can be documented by appended documents.
2. Estimated ability to independent work and ability to formulate and solve scientific questions. This ability can be established, for example, based on a master thesis or in a discussion of scientific problems during a possible interview.
3. Skills in written and oral communication.
4. Other experience relevant to postgraduate studies, such as professional experience.

Other
For all four positions we will apply the same publication and travel rules as is in effect at the division now. These mean that all students get one “free” trip to a major international conference without presenting a paper and after that goes to meetings where the student makes an oral presentation of a paper written by her/him. The normal production for a student is 6-8 papers/presentations as first author within the framework of a Ph.D. Project. All students are also expected to take part in other activities closely related to their own and by that be co-authors of additional papers. The international conferences are located in USA, Asia (Japan mostly) and Europe. Within our wide international network we also send students for 1-6 month periods to companies or universities around the world. Examples during the last year are Toyota (JP), Caterpillar (USA), UC Berkeley (USA), Stanford (USA). This student exchange program is funded by the Vinnova VinnPro framework. Students within KCFP or associated projects will also give presentations for the industry partners twice per year in Lund and also at the industry locations. This means that a good personal network can be built during the Ph.D. Project and thus employment after graduation is highly probable. So far, everybody with a Ph.D. from the division has been offered a position in industry after graduation.    

As a Doctoral student you will mainly be working with your research project, but you can also be given more general tasks within the department i.e. teaching, research and administrative work, in accordance with the regulations. Rules for employment as a Doctoral student is stated in "The Higher Education Ordnance (SFS 1998:80), Chapter 5".

Lund University encourages both men and women to apply for the position.

Salary is determined on an individual basis within certain guidelines for this type of position.

Your application should contain the following documents:
-Letter of application including the correct reference number, PA 2010/144, for the position. (The application should be written in Swedish or English.)
-Curriculum Vitae
-Copies of certificates and copies of any other document that you wish to include in your application.

Application
Application stating the reference number PA 2010/144 should be addressed to the Dean of the Faculty of Engineering at Lund University, and be sent to the Registry Office, Lund University, P.O.Box 117, SE-221 00 LUND Sweden (courier mail to be delivered at: Paradisgatan 5 C). Last day for applying: 5th of February 2010.
