Description
［シミュレーション結果］
算出された平均流速を表３に示す。「ＩＤＢ／ＩＤＴ」欄には、内径ＩＤＴに対する内径ＩＤＢの比を示す。さらに、図１１は、表３中の「ＩＤＢ／ＩＤＴ」と「平均流速（ｍｍ／ｓ）との関係を示す図である。図１１中の横軸は、「ＩＤＢ／ＩＤＴ」を示す。表３中の縦軸は、「平均流速（ｍｍ／ｓ）」を示す。
表３及び図３を参照して、各設定条件ともに、平均流速はプラスであり、いずれの設定条件においても上昇流Ｆ１が形成された。さらに、ＩＤＢ／ＩＤＴ値が０．２５〜０．６５の場合、上昇流Ｆ１の平均流速が１０ｍｍ／ｓ以上であった。さらに、ＩＤＢ／ＩＤＴ値が０．３０〜０．６０の場合、それ以外の場合と比較して、平均流速が顕著に高くなり、２０ｍｍ／ｓを超えた。
[simulation result]
The calculated average flow velocity is shown in Table 3. The “ ID B / ID T” column shows the ratio of the inner diameter IDB to the inner diameter IDT. Furthermore, Fig. 11 is a diagram showing the relationship between " ID B / ID T" and "average flow velocity (mm / s)" in Table 3. The horizontal axis in Fig. 11 is " ID B / ID T". Indicates The vertical axis in Table 3 indicates "average flow velocity (mm / s)".
With reference to Table 3 and FIG. 3, the average flow velocity was positive in all the set conditions, and the upflow F1 was formed under any of the set conditions. Furthermore, when the IDB / IDT value was 0.25 to 0.65, the average flow velocity of the upflow F1 was 10 mm / s or more. Furthermore, when the IDB / IDT value was 0.30 to 0.60, the average flow velocity was significantly higher than in the other cases, exceeding 20 mm / s.
