Abstract(J)CHT解析を用いてエンジン内部の冷却水温を予測しているが,非常に多くの時間を掛け,実測値と同定を取った熱境界条件を用意しなければならない.そこで,重回帰分析と深層学習を組合わせることで説明可能性を高めつつ、高効率化かつ高精度のサロゲートモデルを構築し、熱境界条件の導出を効率化できたことを紹介する.

Abstract(E)Engine coolant temperature prediction utilizes Conjugate Heat Transfer (CHT) analysis. However, identifying the combustion chamber walltemperature based on actual measurements is a time-consuming process. The purpose of this paper is to develop a surrogate model that canpredict the combustion chamber wall temperature faster than conventional methods. We propose that a surrogate model utilizing multipleregression analysis and deep learning can achieve high explanability and high efficiency.

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.
