Presented at the STAR Global Conference 2012 Behr is using various CFD simulation processes and methods within the development process of components for engine cooling applications. In the future STAR-CCM+ is going to be the standard tool for CFD simulations. The biggest challenges within these simulation processes are the stability and robustness of the simulations including the distribution of flow and temperature fields into the fluid as well as the temperature distribution in the adjacent solid. Due to the application of the methods within the standard development process, simulation...
Presented at the STAR Global Conference 2012 Spray nozzles are an important feature of many industrial applications. The traditional way to treat spray is to use Lagrangian particles with a suitable injector modeling in the CFD-simulations. STAR-CCM+ does provide a model (Pressure Swirl Atomiser and LISA-model) for the primary atomization that allows the user to set several spray parameters such as cone angles and mass flows. However, this method is only applicable to a pressure swirl spray nozzle. If a different spray nozzle is to be used a method that relies on experimental data has to be...
Presented at the STAR Global Conference 2012 This presentation describes the research and development work undertaken by the Challenge Italia design team to evaluate alternative designs for the production of the first two prototypes of C Class catamaran to participate in the Little America’s cup challenge in 2013. The use of a robust and versatile CFD suite such as STAR-CCM+ coupled with state of the art Velocity Performance Prediction tools, whose results have been interpreted and analyzed by experts, allowed the testing and comparison of a large number of different hull shapes. This...
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...
