Abstract(J)CO2排出量削減のために空気抵抗(Cd値)の低減は欠かせない。ただしCd値は車体形状に依存するため,デザインと空力の両立が命題である。私たちはタイヤ周りの流れ場に注目し、CFDを活用して検討を行いデザインコンセプトと両立し空気抵抗を低減できる新技術を開発した。そして、新しい技術を新型SUVに適用した。

Abstract(E)Reducing the aerodynamic drag is essential for cutting CO2 emissions. However, the aerodynamic drag (Cd) depends on the geometry of the vehicle, so both aerodynamic performance and the design are necessary. So, we developed new drag reduction technology while realizing the design concept, focusing on the flow around the tire with rotation, with the use of the Computational Fluid Dynamics (CFD). And, we adopted these new technologies on the aerodynamic development of the new SUV model.

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.
