Abstract(J)1Dエンジンモデルで使用するターボモデルの作成工数削減と予測精度の向上を目的として,伝熱に関連するパラメータの同定に機械学習を適用した.タービン出口温度の精度はハウジングからの放熱の他,タービン効率にも大きく左右される.本報ではこの効率にも補正を施すことで,予測精度の更なる向上を試みた.

Translation

Abstract(E)Machine learning was applied to the calibration of parameters related to heat transfer for reducing man-hours for building turbocharger models and improving prediction accuracy used in 1D engine models. The accuracy of turbine outlet temperature is greatly affected by not only heat radiation from the housing but also turbine efficiency. In this report, correcting turbine efficiency was applied for the purpose of further improvement of accuracy.

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.
