中文摘要 | 本文係對流體中之氣泡作穩定性之分析,文中先以氣泡介面之表面張力及介面兩側壓力差間作動力平衡之分析,繼之就上項分析結合氣流內部混合氣之熱力過程尋找氣泡之穩定度。文中並求出熱力過程指數對氣泡成核時之關聯性。本研究結果將有助於了解流體中之孔蝕現象,氣泡之成核,以及準騰過程之起始原因。 |
英文摘要 | The stability of an undissolved gas bubble in a liquid has been studied. The forces form the pressure of the mixture gas inside the bubble and the compression forces outside on the bubble boundary have been formulated. This fluid dynamics analysis was then combined with thermodynamics processes to determine a bubble stability. The heating process index related to the bubble nucleation for a liquid containing dissolved gas is obtained. The results are important to cavitation, bubble nucleation, and boiling processes. |
