While raindrops falling on your head might represent a minor annoyance, the same raindrops accumulating on your car windscreen, or forming as ice on an aircraft wing can represent a serious safety concern. However, until recently simulating multiphase problems such as aircraft icing, vehicle soiling and water management has presented a significant computational challenge, due to the need to model the tiny particles of water as huge numbers of discrete Langrangian droplets. These droplets impinge on key vehicle surfaces, such as aircraft wings and car side mirrors, to form a fluid film or, if...
When you hear the phrase “Volume Rendering”, the first thing that may come to mind is a collection of highly compelling medical images depicting our internal organic structures. You might also recall movie blockbuster special effects showing things like clouds, smoke, storms and explosions. And you might be thinking that these high-end visualizations are the exclusive domain of dedicated medical imaging facilities and animation powerhouses like Dreamworks and Pixar. What would you think about being able to create a “Volume Rendered” depiction of your CFD results on your laptop? And why would...
Great designs aren’t born fully formed and beautiful. They evolve, shaped by exposure to the rigorof real-life operation. Engineers know this. There are few words that cast as much fear into the heart of an engineer as “untested”. From the very earliest days of our careers, we learn the hard way that “untested things”, such as components, ideas and designs, break under the stress of real-life operation. That, in part, is the art of engineering: taking things and making them better, finding out how they break, why they break, and working out clever ways in which to prevent them from breaking...
Recent progress in simulation methods for the manufacturing industry has reduced the need for expensive test hardware which could be used free of charge in manufacturing. Using manufacturing simulation tools starting at the design stage helps to optimize product development and corresponding manufacturing systems. Whenever there is the need for an early design input in order to ensure quality and manufacturing costs virtual manufacturing methods will have a profitable chance. For the case study "E-Coat Simulation" STAR-CCM provides an improved workflow from CAD-data and meshing to E-coat...
Presented at the STAR South East Asian Conference 2013
Singapore is subjected to occasionally sudden and unpredictable rain throughout the year. Addition of architectural elements such as awnings, overhangs and louvers, is a commonly adopted method in reducing the penetration of rain into building spaces. Well designed architectural elements can provide comfort, convenience for the occupants of the building, and at the same time, maximize the use of building outdoor spaces. However, the designs of these architectural elements are often based on prediction. This could be inaccurate and might result in further corrective measures being implemented...
Computational Fluid Dynamics (CFD) is an effective tool to tackle various types of building systems. For the master planning of a city, CFD can be used to study the airflow around buildings to improve pedestrian wind comfort. From the study, design optimization works can be done on improving the building orientation and the massing of the building. Building occupants’ thermal comfort can then be further improved with natural ventilation studies on the internal layout in the building. Other than natural ventilation simulations, CFD can also be used as a tool to optimize designs for mechanical...
An overview of the challenges of FSI will be presented along with the capabilities available in STAR-CCM+ to meet those challenges. The topics will include: a) Data mapping techniques b) Protocols and formats for exchanging data between CFD and CSM codes c) Coupling methods for stability and accuracy d) Techniques for dynamic fluid mesh evolution e) Validation of FSI results A technical overview under each of these topics will be provided. A range of examples which demonstrate the STAR-CCM+ FSI capabilities and validate the accuracy will be shown. The examples span analytical and experimental...
Presentation of the wide spectrum of methods available in commercial CFD software; from steady-state stochastic/correlation models to fully transient resolution of the flow and acoustics features using compressible CFD and LES-based turbulence modeling. We include case studies from many engineering sectors like automotive, aerospace, marine and power generation, finally focusing on the study of a generic side-view mirror, intended for validation of the flow mechanisms, and data analysis using temporal and spatial Fourier analysis aimed at understanding the separable excitations of the...
This presentation will give academics an opportunity to learn more about the CD-adapco Global Academic Program which provides software, training, support, teaching modules and more to our global academic community. Working closely with hundreds of leading academic institutions around the world to introduce STAR-CCM+ into the classroom, labs, capstone design and student competition teams we are helping to prepare students for a successful engineering career in industry.
