Abstract(J)自動車開発における空力検討期間の大幅な短縮を達成するために,車体形状に対する3次元流れ場を短時間で出力可能な空力サロゲートモデルを構築した.また,この空力サロゲートモデルを実際の開発に適用するために,流れ場を3つの成分に分割するLocal dragを用いた評価手法と組み合わせた.

Translation

Abstract(E)We have developed an aerodynamic surrogate model capable of rapidly outputting 3D flow fields for vehicle shapes to achieve a significant reduction in the aerodynamic evaluation period. Furthermore, we have combined it with an evaluation method that utilizes Local drag, which divides the flow field into three components to facilitate the practical application in actual development processes.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
