CD-adapco is First to Introduce an Integrated Environment for Fluid Flow and Structural Analysis New York and London. June 24, 2015 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). The highlight of the v10.04 release is an entirely new Finite...
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。
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...
This thesis investigates the application of jet streams to generate a surface lm ow for the cooling of solid non-salient pole rotors of electrical machines. It should be taken advantage of the Coand -eect to generate the lm ow on the surface of the rotor. Flow simulations are carried out to examine the ow in detail. Variation of inuence parameters with assistance of axisymmetric models results that there is no signicant inuence of the rotor speed. When raising the mass ow rate of the jet stream an enhancement of the heat transfer coecient can be observed. Besides that, a reducing of the inlet...
Improving heat transfer in helical tube heat exchanger is studied, experimented and analyzed by many research peoples, it’s because the fluid passing through the helical tube offers certain better advantages then straight tubes. in this paper we are concentrating on improving shell side heat transfer coefficients and net heat transfer in given experimented model, without much pressure loss is our main aim of project. So we are referring some journals for correlations of AL2O3 nanofluids properties and designing the model in ANSYS WORKBENCH 15 then it is meshed and solved in STARCCM+ solver...
