Abstract(J)LES乱流解析による燃焼室内の温度分布と壁面熱流束の実験データと比較し火炎の挙動と壁面熱伝達の関係を考察した。LIBS法(レーザ誘起ブレイクダウン分光法)を用いて、各原子発光強度の評価を最適化することにより、高濃度領域および圧力やレーザエネルギの変化の影響を受けない局所当量比の測定が可能となった。

Translation

Abstract(E)The flame propagation process in the combustion chamber with sub chamber of RCEM (Rapid Compression Expansion Machine) was analyzed by using LES turbulent flow simulation and the results were compared with visualization by OH self-emission. And some data of new measurement methods for equivalence-ratio and wall temperature using LIBS (Laser Induced Break-down Spectroscopy) and Phosphor Thermometry method will be introduced.

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.
