STAR-CCM+ v10.04 delivers two new features to help streamline your process for extracting the right information from your simulations. We have added an option to store a history of simulation data at the boundaries only, resulting in a significant savings in disk space and a substantial reduction in time to navigate the stored results. We have also added custom summaries, to enable you to choose exactly what content you want to save from your simulation file in a customized HTML report. With custom summaries, you’ll be able to focus on fewer details, resulting in more effective and efficient communication of the key elements of your simulation efforts.
Better Products Faster through Multidisciplinary Design Exploration
With ever more powerful computer hardware available and increased access to easy-to-use analysis environments, engineers now have the tools available to gain insight into product behavior like never before. The question is, how do you take that insight and use it to not only understand the behavior, but to improve it? Furthermore, how can design exploration help? This webcast demonstrates how advancements in simulation are allowing engineers to make better designs through multidisciplinary design exploration. Included in this will be the use of the adjoint solver for sensitivity analysis and...
Practical application of Computational Fluid Dynamics (CFD) for predicting flow pattern around a ship hull and calculation of total resistance has been a topic of great interest for researchers in ship hydrodynamics. Today, several CFD tools have been developed to analyse and capture the free surface around a ship. The flow problem is rich in complexity and poses many challenges during simulation. Many mesh sizes were tried during modelling with Realizable k-epsilon and shear stress Transport (SST) k-omega turbulent models. The free surface wave pattern and the total resistance (shear and...
A direct numerical simulation was used to study the buoyancy driven turbulent flow inside a horizontal annular cavity at Rayleigh number, Ra = 1.18 × 10 9 , and cylinders diameters ratio of 4.85. Mean and rms temperature profiles are in good agreement with experiments. Turbulent kinetic energy budgets have been calculated to verify the accuracy of the unstructured finite volume code on polyhedral cells in Direct Numerical Simulation (DNS) mode. The code is found to return satisfactory results for first and second order statistics, and coherent turbulent kinetic energy budgets, except for the...
Wind turbines release aerodynamic noise that is one of the most barriers in wind energy development and public acceptance. Aeroacoustics is the noise generated by the interaction of blades, specifically the tip and trailing edge, with inflow turbulence structures and subsequent boundary layer separation and vortex shedding in the wake region. The objective of this study is to analyze the effects of different aerodynamic conditions on the performance and the aeroacoustic issue of wind turbines. Aerodynamic and aeroacoustic operation of a wind turbine is analyzed using a three-dimensional CFD...
CD-adapco, the largest privately held CFD-focused provider of Computer Aided Engineering software, today announced the release of STAR-CCM+® v10.04, the second release in 2015 of its flagship simulation tool. The latest release represents a major step forward in the company’s vision of allowing its customers to “discover better designs, faster” using Multidisciplinary Design eXploration (MDX).
STAR-CCM+を活用した熱流体解析対象拡大の一貫として、融解固化モデルによる適正鋳造条件絞込みへの適用性について検討した。本発表では、鋳造製品のひとつとしてコンロッドを対象とした。VOF法と凝固モデルを使用することで溶湯の自由表面と固相率増大に伴う流動性低下現象を確認した。注湯された溶融金属の湯流れや鋳型への充填状況や凝固界面移動過程の解析、溶湯未充填領域の発生抑制などの取組んだ事例について紹介する。
This presentation will give a brief overview of the multiphase models in STAR-CCM+, from Eulerian-Eulerian to Lagrangian-Eulerian, including DEM.
The location of the air intake of a bus creates challenges from a soiling perspective. The proximity to the rear wheels pulls up dirt from the road. Compared to a commercial truck, with the fan placement in the front of the vehicle the air intake of a bus can’t rely on ram air pressure to get the sufficient cooling air mass flow. The fan must always operate on high effect when the bus is driving and thus pulls in dirt. An understanding of the flow of the dirt in the engine is necessary for a possibility to prevent it from soiling the engine compartment. As physical evaluation of the dirt flow...
