Most new engines will use direct injection of the fuel, making the fuel spray a critical part of the engine. Fuel spray behavior controls engine performance and emissions, and yet there is much that remains unknown about how a spray breaks up, mixes, evaporates and burns. This project will provide experimental support for the development of new computational models that are both efficient and more predictive than in the past. Without predictive models it will be impossible to optimize combustion computationally.
As a PhD student, you would start in the spring or summer of 2013. Your experimental research would be on the basic fluid mechanics of spray breakup, which is related to most forms of combustion engines. We will isolate basic breakup modes (e.g. turbulence, cavitation, shear etc.) in steady sprays and study them in significant detail. The group has advanced measurement capabilities that do not exist anywhere else, and our experiments will be tightly coupled to computational model development.
Design new spray experiments
Perform detailed measurements (mostly laser based) on each spray
Work with CFD model developers to help them improve their models
The project is funded by the Swedish Energy Agency but it is coupled to a much bigger grant from the Knut and Alice Wallenberg (KAW) foundation. The grant from the energy agency will pay the student salary and associated costs, while the KAW grant will pay for a post-doctoral scholar who would provide support to you, a team of model developers, and serious investment in new experimental facilities. Chalmers has a unique laser diagnostic technique for imaging how a spray breaks up, and we already have a PhD student who works with that technique. You would partner with the existing student and the post-doc.
You should have a Master of Science (Swedish: civilingenjör exam; a four year US bachelor’s degree meets the minimum requirement), preferably in Mechanical Engineering or with a similar background. Knowledge fluid mechanics is considered essential. Knowledge of optical measurement methods is seen as an advantage. You will collaborate with several research partners, so the ability to cooperate is considered very important. As a PhD student you are expected to work relatively independently, have ability to plan and organize your work, and be able to communicate your scientific results, both orally and in writing, in English. Knowledge of the Swedish language is desirable but not a requirement. However, all PhD Students are expected to be able to teach in Swedish as well as in English after two years of employment. Those who do not have Swedish as their mother tongue are offered courses in the Swedish language.
Details about employment as a PhD student at Chalmers
The PhD student employment is limited to maximum five years and will normally include 20 percent departmental work, mostly teaching duties. The salary for the position is specified in Chalmers' general agreement for PhD student positions. Chalmers ( http://www.chalmers.se ) is a semi-private university offering degrees in science, engineering and architecture. It is located on a hill near the center of Gothenburg, the second largest city in Sweden ( http://www.goteborg.com/ ). Graduates of this program go on to positions in academia, research labs, and industry. Many find employment at Volvo Car and Volvo Truck (located in Gothenburg), Scania (just south of Stockholm), and others. Gothenburg is located on the west coast of Sweden nearly midway between Copenhagen, Denmark and Oslo, Norway. It is Scandinavia’s largest port city with around 600,000 inhabitants. Gothenburg has a lively nightlife in addition to many outdoor opportunities. The archipelago just outside of the city is wonderful for sailing. To the east one finds open country filled with hills and lakes. To the north one finds mountains (including good deals at ski hills in Norway) and wilderness, and to the south one finds the rest of Europe (with cheap flights to most destinations).
