A theoretical model to predict the rising trajectory of single bubble with zigzagging path in still water
The rising motion of single bubble in still liquid is a natural phenomenon, which has high theoretical research significance and engineering application prospect. Experimental observations and numerical simulations for prediction of the rising trajectory of a single bubble in still liquid are being carried out, while the concise but accurate theoretical or mechanism model is still not well developed. In this article, a theoretical model of a single bubble based on experimental observation of flow around bluff body is proposed to predict the rising trajectory of zigzagging bubbles in still water. The prediction correlation of bubble lateral movement frequency and bubble steer angle are established based on three degrees of freedom frame. The model has achieved good trajectory prediction effect in the bubble rising experiment. The average simulation time per unit moving time of bubble is 2.5 s.
期刊介绍:
The Chinese Journal of Chemical Engineering (Monthly, started in 1982) is the official journal of the Chemical Industry and Engineering Society of China and published by the Chemical Industry Press Co. Ltd. The aim of the journal is to develop the international exchange of scientific and technical information in the field of chemical engineering. It publishes original research papers that cover the major advancements and achievements in chemical engineering in China as well as some articles from overseas contributors.
The topics of journal include chemical engineering, chemical technology, biochemical engineering, energy and environmental engineering and other relevant fields. Papers are published on the basis of their relevance to theoretical research, practical application or potential uses in the industry as Research Papers, Communications, Reviews and Perspectives. Prominent domestic and overseas chemical experts and scholars have been invited to form an International Advisory Board and the Editorial Committee. It enjoys recognition among Chinese academia and industry as a reliable source of information of what is going on in chemical engineering research, both domestic and abroad.
