reynold numberとは 意味・読み方・使い方

An experimental result implies that enhancement of the heat transfer efficiency due to the protrusions is obtained in the low Reynold's number division in which the Reynold's number Re of the fluid flowing inside is below 7000, and that the effect of the protrusions on the pressure loss inside the tube is suppressed, to lead to enhancement of the performance of the whole heat transfer tube.例文帳に追加

実験の結果、内部を流れる流体のレイノルズ数（Ｒｅ）が７０００未満の低レイノルズ数区間で、管内に設けられた突起により、管内に設けた突起による熱伝達率の向上が図られるとともに、突起が管内の圧力損失に与える影響が抑えられ、給湯用伝熱管全体の性能が向上する。 - 特許庁

To provide a heat transfer tube for supplying hot water embodied in a simple construction, having a small pressure loss inside the tube, and capable of enhancing the heat transfer performance in the low Reynold's number region.例文帳に追加

簡単な構造で、低レイノルズ数域において伝熱性能の向上を図るとともに、管内の圧力損失が小さい給湯用伝熱管を提供する。 - 特許庁
