Abstract(E)With the electrification of automobiles, cabins have evolved into advanced interior designs, and the energy of vehicle components has been minimized. HVAC has redesigned its traditional semi-center layout to come up with a full-center layout. To realize this HVAC, a turbo fan was adopted. In order to solve the problem of noise, the noise source was identified by visualizing the actual rotating fan blade flow, and the flow separation in the blade was controlled using unsteady CFD. As a result, the blower volume decreased by 40%, the specific noise level decreased by 2dB, and the power consumption decreased by 30%.

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.
