中文摘要
本論文是以數值分析模擬過飽和液體在固化過程中界面氣泡成長的流場與濃度場。液體的過飽和會產生氣泡。此現象在不同領域經常產生,例如熱傳、製造、生化等。本研究是以微觀理論分析探討單一氣泡生成後隨時間變化為氣孔,其各種現象所產生的變化,及對濃度及流場分布,與氣泡所受的升力與阻力等相互之間的關係。氣泡形成時之不同條件包括液體衝擊速度、氣泡接觸角等。本論文結果將有助於了解及改善氣泡生成之機構,對於科技產業將有相當大的幫助。
Abstract
This paper numerically simulates flow and concentration fields in a supersaturated liquid in front of the solidification front during freezing. The supersaturated liquid usually produces bubbles. This phenomenon often occurs in different fields, for example, heat transfer, manufacture, biochemistry , etc. The research is based on micro theory to analyze different phenomena of a single bubble, which involve the unsteady interactions between flow and concentration fields, and rising and resistance forces etc. The results contribute to an improved understanding of bubble dynamics generally encountered in technological industries.
