Abstract(J)水素直噴エンジンにおいて筒内の水素と空気の混合気形成は燃焼安定性のために重要な要素である.筒内混合気形成の把握には筒内CFDが利用されるが筒内での水素拡散現象の検証は不十分である.本研究では可視化エンジンにより筒内のシュリーレン撮影を実施し水素拡散を把握し,エンジン筒内解析における水素拡散予測の精度向上を検討する.

Translation

Abstract(E)In a hydrogen direct injection engine, the formation of a mixture of hydrogen and air in the cylinder is an important factor for combustion stability. Though in-cylinder CFD is utilized for grasping in-cylinder mixture formation, verification of hydrogen diffusion phenomenon in the cylinder is insufficient. In this study, the schlieren image in the cylinder is taken by the visualization engine to grasp the hydrogen diffusion, and the accuracy improvement of the hydrogen diffusion prediction in the engine cylinder analysis is examined.

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.
