Abstract(J)	ピストンリング周辺の潤滑油輸送メカニズムの把握に向けリング溝内に着目した二相流シミュレーションを実施した。気液界面と物体境界の定義にLevel set法およびGhost cellを用いるプログラムを開発した。本研究では3ピースオイルリングの周辺に着目した二次元の計算領域を対象とし、ピストン下部からリング溝内に流入する潤滑油の挙動に関する解析を行った。本稿ではクランク回転数の変更によるピストンの加速度の変化が潤滑油に与える影響について述べる。 Translation

About search

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
