Abstract(J)	超臨界流体は臨界点以上の流体と定義されており，冷媒や溶媒として様々な応用技術が提案されている．我々の研究グループでは超臨界流体シミュレータを構築して，超臨界二酸化炭素や超臨界水，超臨界炭化水素の臨界点近傍における流動の解明を図っている．本稿では超臨界流体シミュレータのこれまでの応用事例を紹介する． Translation
Abstract(E)	Supercritical fluid is a state above the critical point, and the thermophysical properties change drastically near the critical point. Supercritical fluids have utilized in many industrial processes as a solvent or coolant. We have developed supercritical fluids simulator to investigate transcritical and supercritical fluid flows in industrial applications; supercritical CO₂ flows in radial compressors, supercritical H2O flows in chemical reactors, and supercritical hydrocarbon flows in a cooling channel. The numerical method and numerical results by supercritical fluids simulator were introduced.

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".
