Description:
The Rolls-Royce University Technology Centre at Chalmers is a centre of excellence specializing in computational hydrodynamics. It was founded by Rolls-Royce in 2002 and works in close cooperation with Rolls-Royce companies in Sweden, Norway and Great Britain. The aim of the Centre is to study the flow around ship hulls and propulsors of different kinds like ordinary screw propellers, water-jets or pods. A substantial part of the activity involves developing and evaluating computational tools based on RANS or LES techniques to simulate this flow. The centre is located at the Department of Shipping and Marine Technology, Division of Sustainable Ship Propulsion.
At present, PhD student positions are open in four research projects at the Centre. The projects are described below.
1. Numerical modelling of cavitation using LES
This project includes pure numerical developments like sliding mesh techniques for coupling rotating and non-rotating grids, adaptive grid refinements and load balancing, but also physical modelling of cavitation using a dynamic model for computing pressure fluctuations on the ship hull and its propeller. The work will be carried out in OpenFOAM.
2. Optimization of hull/propeller/ rudder interaction
This is a continuation of a project which was finished in June 2008. By coupling a RANS method (SHIPFLOW, developed in-house), a propeller analysis code and an optimizer the rudder was optimized behind the hull and the propeller. In the new project the hull and the propeller will be optimized as well, which will call for a link to a CAD program for describing the hull shape.
3. Basic studies of waterjet propulsion
In waterjet propulsion the water is sucked in through an intake at the bottom. This causes a change in the pressure and velocity distributions around the hull and thereby also in its sinkage and trim. All these changes have an influence of the resistance. The purpose of the project is to study the effects of the intake in detail though CFD computations, in which the external flow around the hull is coupled to the internal flow through the pump.
4. Development of a new propeller concept
Traditional propellers have developed over a long period of time and it is difficult to significantly increase their efficiency. In this project a new propeller concept will be evaluated using RANS techniques and experiments. This is an advanced RANS application and some development of the RANS method (SHIPFLOW) may be required.
PhD students at Chalmers are employed and receive a regular salary, at present around 25 000 SEK (about 2400 EUR) per month. The employment is limited to five years, and 20% of the working time may involve departmental duties, mainly teaching. More information on the PhD education can be found at:

Since the teaching will be within our Naval Architecture program an education as a Naval Architect is an important merit, particularly in combination with an interest in yachting. Chalmers Naval Architecture program is one of the few in the world with a specialization in Yacht Design. Applicants with a Master of Science in Mechanical Engineering, Engineering Physics, Engineering Mathematics or similar are also well qualified for the positions.
