Presented at the STAR Global Conference 2012 STAR-Cast’s multiphase approach, the HRIC algorithm for interface capturing, the advanced meshing techniques and the STAR-Cast power session are the key features in rigorous simulation of HPDC processes. The predominant process input parameter is the shot curve, which determines melt flow from the filling chamber via controlled piston movement into the mold insert, and thus the compression and outflow of air. All input parameters can be defined via the STAR-Cast graphical user interface for HPDC-processes: the cooling and heating system conditions...
Presented at the STAR Global Conference 2012 Centrifugal casting processes are widely employed to manufacture stainless steel components, steel rollers or high precision components involving very thin geometrical dimensions. Due to high centrifugal forces very dense and pure material structures can be obtained. STAR-Cast’s multiphase approach along with the advanced meshing technology is necessary to predict casting defects like misruns. The first necessary step is to obtain a sharp metal-air front during filling. This is ensured by the state-of-the-art High-Resolution Interface-Capturing (...
Presented at the STAR Global Conference 2012 This presentation explores the analysis of the airstream in a roller dynamometer at the Engineering Center Steyr, which is mainly used as a testing facility and engineering tool for vehicles. To ensure that vehicles being tested are adequately cooling, a CFD simulation of roller dynamometer predicts the airflow in the building. In order to achieve realistic results, the simulation model of the empty roller dynamometer building is first created from measurements before a virtual vehicle is imported into the roller dynamometer building. These results...
Presented at the STAR Global Conference 2012 Simulation and computational models are rapidly becoming essential predictive tools for a large number of industry segments. The overwhelming majority of 3D CAE models requires the usage of a computational grid whose characteristics strongly affect the quality of the predictions and finally the market competitiveness of the products. CD-adapco spends a significant part of its resources in innovating the volume meshing offered in STAR-CCM+. A brief overview of the ongoing research projects in this area will be presented with focus on parallel and...
Presented at the STAR Global Conference 2012 A methodology will be presented which allows the prediction of the accumulated effects of environmental impacts such as solar radiation, temperature and humidity on components of a given material, geometrical, geographical and environmental configuration as well as exposure time. The procedure relies upon simulation using STAR-CCM+ to obtain the exact micro climate around the component. All relevant physical phenomena such as solar and heat radiation, shadowing, conduction and convection are taken into account. In order to simulate the overall...
Presented at the STAR Global Conference 2012 Three-dimensional CFD simulation is increasingly achieving acceptance for a wide range of applications in civil engineering. A brief overview is given by means of projects from a variety of backgrounds that have been worked out within the past year. From the tap to the drain! This is the basic picture we have of our water supply cycle. Just the experts know about the reverse of the complex systems behind these two interfaces like waste water treatment and fresh water supply. VoF enables us to provide an extensive insight into what is behind tab and...
Presented at the STAR Global Conference 2012 Active Space Technologies GmbH is performing a simulation of a building subject to conjugate heat transfer involving radiation, convection, conduction and mass transfer. The building is located in a village in southern Spain. The scope of the project is to analyze the effect of nano-materials added to paint for external walls, as well as to tile facades in order to improve the reflective properties of the building at near-infrared wavelengths. Additionally, the the aim is to obtain energy savings for the buildings’ cooling system. In order to...
Presented at STAR Global Conference 2012 This presentation will report some of the conclusions from the 2 year project including Porsche, GM Opel and Daimler. The project is managed and led by the Automotive Simulation Centre Stuttgart. The project is a rigorous study into the application of simulation technology to a previously designed lithium ion battery pack. The presentation will feature comparisons of test work and simulated results at both the cell and module level.
Presented at the STAR Global Conference 2012 With the advent of vehicle electrification, driven largely by advances in Li-ion battery technology, there is an increasing need for the type of predictive simulation tools that are commonplace in the virtual vehicle development process for classical ICE-propelled automobiles, such as crash, aerothermal and combustion simulation. Such tools are necessary in order to make the overall development effort and cost of electric traction systems competitive by reducing the test and design loops. Aiming to establish a multiscale simulation process chain...
