摘要

本研究是係蒐集以電化學實驗的方法探討熱質自然對流現象之論文、研究計畫及發表之期刊文章加以分析整理，並探討其演化過程，以Pr在7~8之間，針對不同浮力比（N值）、邊界條件所展現的流場型態，提出詳細參數效應，如涉及自然對流幾何形狀密閉盒之展弦比、傾斜角度、隔板數、隔板位置等與實驗裝置、溶液溫度及濃度的變化情形，以系統化觀點作為研究的方向。
本研究首先針對熱質自然對流現象論文作分類，再以各個邊界條件參數變化作比較，加以整理分類以期獲得自然對流研究之個別現象顯現。以了解在不同時期，如何依學理上之考量設計，對無因次參數變化研究範圍，以獲得持續發展之脈絡。

This research collected all literatures on thermosolutal natural convection in an electrochemical system including journal paper, thesis and studies evolution processing, the prandtl number are between 7and 8, to counter different buoyancy ratio and boundary condition of the flow structure. The purpose of this research is to give a detailed summary of the effect of several parameters such as thermalsolutal natural convection of the test cell geometry aspect ratio, inclination angle, partition number, partition shape, partition position and the temperature distribution and the concentration distribution varied will be employed a point of systemized view in this research.
This research is to classify thermosolutal natural convection thesis, to compare boundary conditions with each other and to summary resultant from each case, this why we want to get sequence development to decide dimensionless parameters range with respect to the design basis during different period.
