Abstract(J)発表者らはVoF法をベースとした燃料微粒化解析のための二相流詳細解析ソルバを開発してきた。本発表では、本ソルバと大規模計算機によるディーゼル噴霧の一次微粒化詳細解析を実施し、その微粒化過程の特に粒形分布と個々の液滴の幾何形状に着目した評価を行ったので報告する。

Translation

Abstract(E)The authors have developed a detailed flow analysis solver of two-phase flow based on the VoF method for fuel atomization analysis. In the presentation, a detailed analysis of diesel spray was conducted, and evaluation was carried out focusing on the particle size distribution and geometry of each droplet in the primary atomization process.

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.
