Abstract(J)	空力およびエンジンルームの冷却を両立する最適形状を得るために，HPCを用いた最適化を実施した．形状モーフィング，CFD，進化計算により構成された最適化フローを，CD値および各熱交換器の通過風速の多数目的最適化に適用することで，ベース形状よりもすべての性能を向上することができる複数の最適解が得られた． Translation
Abstract(E)	To obtain optimal designs which satisfy aerodynamics and underhood cooling airflow for a detailed full-vehicle model, a shape optimization method using HPC（High Performance Computing）is performed. The shape optimization workflow integrated with shape morphing, CFD（Computational Fluid Dynamics）and evolutionary computation was applied to a many-objective optimization for Cd and airflow velocities through heat exchangers. The result showed several optimal designs which all objectives are improved from the default.

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".
