Presented at the STAR Global Conference 2012 This presentation addresses the shape optimization of a monohull fishing vessel for multi-objective purpose - resistance and sea keeping – including extensive Computational Fluid Dynamics (CFD) calculations with STAR-CCM+. Design variations, objectives and constraints are set up in collaboration with the naval architect. To solve this problem, a complete optimization chain involving different tools as been developed, namely a CAD tool (Catia v5), a frequency-domain linear seakeeping code (Aqua+), two software tools with different levels of...

Presented at the STAR Global Conference 2012 The use of cavitation modeling within the maritime industry area is in a crucial state. The advances in the computer power, the understanding of the numeric’s and cavitation phenomena do make possible to bring these kinds of simulations into the daily use. The general goal within the marine industry is to have a numerical tool which can predict the accurate behavior of cavitating flow both in design stage and for problem solving situations. In this presentation results will be shown of cavitating flow obtained with STAR-CD, for a two-dimensional...
Presented at the STAR Global Conference 2012 Increasing the efficiency for future steam cycle power plants is of significant importance for the reduction of their CO2 emissions. Today’s best steam cycle power plants have a net plant efficiency of 46% while the average efficiency value for such power plants worldwide is still around 30%. Consequently, there exists a great potential for a reduction in CO2 emissions by replacing old power stations with new ones. Yet, a greater potential can be achieved if even higher efficiencies are obtained. In order to push the efficiency of stem power plants...
Presented at the STAR Global Conference 2012 The efficiency of generating units is of great economic importance to the operation of hydropower. Even a small improvement in their efficiency leads to a significant economic effect. Numerical simulation of the hydro turbine has many advantages over experimental studies. In this presentation the process of modeling the flow in a hydrоelectric generator will be outlined. Different configurations of stator and rotor blades were investigated numerically. Parameters relevant to efficiency and performance were obtained and analyzed. The focus is on a...
Reacting flow modeling in STAR-CCM+, Presented at the STAR-Japanese-Conference
Presented at the STAR Global Conference 2012 The power electronics system of an electric vehicle is a critical part of the electric drivetrain, controlling the electrical power delivery between the battery system and the electric motors. IGBTs (insulated gate bipolar transistors) are three-terminal power semiconductor device primarily used as an electronic switch combining high efficiency and fast switching. IGBTs are a key component in the power electronics system, and this presentation will give specific instructions for effectively and efficiently simulating the thermal performance of...
Presented at the STAR Global Conference 2012 With the rise of portable appliances, hybrid & electric cars and storage systems for renewable energy sources, Li-ion batteries have proven to be the most relevant storage device for these applications. As a consequence of this increased interest, the need for more efficient, safer and longer life cells is clear. However, designs and test methods for new products are very expensive. A trend is emerging towards simulation, which represents a very cost and time effective alternative or compliment to design and test processes. Simulation solutions...
Presented at the STAR Global Conference 2012 An introduction to batteries is provided, including an overview of the commercial value of batteries sold by chemistry.

Presented at the STAR Global Conference 2012 Regulatory efficiency requirements for electric machines and tremendous price rise in material costs of permanent magnets are a two important motivators for analyzing the thermal performance of electric machines in greater detail. SPEED offers thermal circuit simulations to look at component temperatures during drive cycle load conditions. This is a typical thermal simulation approach for small and medium size machines. For large machines a complete CAD model needs to be built and multiphase flow calculations are performed. A process where we can...
