Abstract

Under the dual-carbon background, the technological updating of traditional high-energy-consuming equipment should not be delayed, and the problem of reactor energy consumption should not be ignored. Therefore, this study is based on computational fluid dynamics (CFD) theory to simulate the spiral stirred reactor with different design parameters (distance of paddle from bottom surface to reactor height ratio h₁/H, diameter of stirring paddle to reactor diameter ratio D_s/D, length of blade section to reactor height ratio L_s/H). It was found that the reactor designed with lower L_s/H values and higher h₁/H, D_s/D values would have smaller power number (Np) values and smaller flow field average velocity. In addition, this study also fitted the correlation equation of Np concerning Reynolds number and h₁/H, D_s/D, and L_s/H, and the conclusions of the study can be used as a reference for the design of industrial equipment.

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.
