Abstract(J)潤滑油消費の要因となるピストンリングまわりの潤滑油輸送メカニズムの把握に向け,3ピースオイルリングを対象とした混相流解析を行った.解析手法には気液界面の明確な定義が可能なsharp interface modelに基づくlevel set法を用いた.本研究ではエンジンの運転に関する諸条件がリング周辺の各部における流量等に及ぼす影響について検討した.

Translation

Abstract(E)A multiphase flow simulation around a three-piece oil control ring was conducted to understand the oil transport mechanism, which is a cause of lubricating oil consumption. We applied the level set method based on the sharp interface model, which provides a precise definition of the gas-liquid interface. The effects of engine operating conditions on the flow rate and other factors at various locations around the ring were investigated.

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.
