CFD（数値流体力学): 四面体及び六面体を含む非構造格子による境界層の解像: オンデマンド・ウェビナー

CFD Japan

境界層に六面体セルを使用すると、ロバスト性と精度が向上するため、CFD実務者には好まれていますが、それだけではありません。従来、境界層には六面体による構造格子（マップド・メッシュ）が使用されていましたが、効率的に作成するには多くの手作業が必要になります。四面体及び六面体を含む非構造格子によるメッシング手法は、非構造格子の柔軟性とスピード、そして六面体セルの品質という2つの長所を兼ね備えています。このオンデマンド・ウェビナーでは、Pointwise（ポイントワイズ）に搭載されている4つの機能を...

CFD（数値流体力学): NUMECAの最適化ソリューションで産業用ブロワーの性能を向上

CFD Japan

石油化学をはじめとする産業分野では、空気の換気から500℃以上の有害な塩素ガスまで、様々なガス処理プロセスにファンが活用されています。これらのファンの最大回転速度は、業界標準で規定されており、多くの場合、制限されています。この回転数の制限により、ファンメーカーは所望の出力を得るために、インペラ（羽根車）の直径を調整しなければなりません。結果的に形状が大型化して重くなり、製造、試験、輸送にコストがかかることがエンジニアにとっての課題ですイリノイ州ケーリーに本社を置くIllinois Blowe...
