Abstract
In this paper, the theory of fluid flow and heat and mass transfer in chemical engineering is discussed in depth, aiming at improving the efficiency and economy of chemical process. The second chapter elaborates the basic theory of fluid flow, including the basic concept of fluid mechanics, the classification of fluid flow, the mathematical desc ription of fluid flow and the experimental research method of fluid flow. Through the in-depth analysis of the fluid flow theory, it provides a solid theoretical basis for the subsequent study of heat and mass transfer. The third chapter focuses on the theory of heat transfer, discusses the basic mode of heat transfer, the mathematical desc ription of heat transfer, the factors affecting heat transfer and the experimental technology and equipment of heat transfer. Through the systematic analysis of heat transfer process, this chapter reveals the key influencing factors of heat transfer efficiency. The fourth chapter focuses on the theory of mass transfer, discusses the basic concept of mass transfer, the mechanism and model of mass transfer, the calculation and influencing factors of mass transfer coefficient, and the engineering application of mass transfer process. Through the in-depth study of mass transfer process, the paper provides theoretical guidance for mass transfer in chemical process. In chapter 5, the interaction between fluid flow and heat and mass transfer is discussed, the influence of flow on heat transfer, heat transfer on flow and the coupling effect of mass transfer on flow and heat transfer are analyzed. This chapter provides theoretical support for the optimization of flow and heat and mass transfer in chemical process through the analysis of coupling effect. The sixth chapter focuses on the optimization design of fluid flow and heat and mass transfer, including the theoretical basis of optimization design, fluid flow optimization design, heat and mass transfer optimization design and optimization design case analysis. A series of strategies to improve the efficiency and economy of chemical process are put forward through the systematic study of optimization design. Through the case analysis of optimization design, the effectiveness and practicability of the proposed method are further verified, which contributes to the technological progress and economic benefit of the chemical industry.
