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. Opportunities for battery simulation in various markets (automotive, consumer, industrial, etc.) are presented, along with examples of the STAR-CCM+ BSM module and Battery Design Studio.
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...
Presented at the STAR Global Conference 2012 SPEED is the most advanced analytical electromagnetic package dedicated to the sizing and performance analysis of electric machines. Motor-CAD software is the unique software for the analytical lumped circuit thermal network analysis of electric machines. Motor-FLOW is a software package which enables the use of special graphical models such as efficiency maps and is designed to automate SPEED and Motor-CAD software packages. This presentation gives details on using together SPEED and Motor-CAD as a multi-physics environment where it is possible to...
Presented at the STAR Global Conference 2012 This presentation shows an optimization tool named BCS (Best Configuration Searcher) specifically developed to obtain in the optimized design of electric rotating machines. This tool works linked to the SPEED software. BCS achieves the goal to give a first optimized design of the electric rotating machine in a very short time, starting from a first idea of the designer. It has a very intuitive interface, suitable for an easy and guided choice of optimization parameters, constraints and final objective. It takes advantages of the SPEED computation...
Presented at the STAR Global Conference 2012 SPEED has been the leading machine design software over the last three decades. SPEED helps the engineer in developing his permanent-magnet or electric excited-dc brushed or brushless machine as well as synchronous machines, induction machines, switched and synchronous reluctance machines including the drive. SPEED is used to design the electrical machine in whatever application: automotive, aerospace, industrial and automation, domestic appliances, power tools, medical systems and much more. This presentation will give a first introduction to the...
Presented at the STAR Global Conference 2012 Computational modeling of combustion processes of diesel fuel serves as a practical tool to gain insight and to optimize the design of engines of tomorrow. However, in order to provide reliable predictions, models need to account for the detailed evolution of a large number of chemical species in addition to complex sub-processes such as turbulence and heat transfer occurring in an engine. This not only implies that the modeling of actual fuels is formidable, but also that much data is unavailable. Therefore resort could be made to surrogate fuels...
Presented at the STAR Global Conference 2012 In this presentation the application of a direct injection stochastic reactor model (DI-SRM) to simulate diesel engine performance parameters and exhaust emissions will be illustrated. The DI-SRM has been applied to simulate diesel and n-heptane fuelled engines at different load conditions. The skeletal mechanism of n-heptane has been used as a main fuel model. Furthermore, investigations have also been performed with several fuel models alternatively to n-heptane that is commonly used to simulate diesel engines. Subsequently, to improve the...
