Translation

Abstract(E)This study proposes an efficient HVAC duct design method based on fluid topology optimization. Conventional design relies on iterative CFD analysis and CAD modifications, resulting in high development effort. The proposed workflow enables automatic generation of optimized duct geometries while incorporating outlet boundary conditions, including downstream register effects. The results were validated through experiments using 3D-printed prototypes and a component test bench. It was demonstrated that outlet boundary conditions have a significant impact on pressure loss and optimized shapes. The proposed method improves performance under realistic operating conditions and reduces development effort by approximately 24 hours per phase.

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.
