Computational Fluid Dynamics in Research and Design of Heat Exchangers

Abstract

This paper gives a brief summary of computational methods in heat transfer equipment, such as CFD (computational fluid dynamics), methods for thermal problems (computational heat transfer), and turbulence modeling for single-phase applications in the design, research and development of heat exchangers. Details of the finite volume method and their extension to arbitrary geometries are presented. An overall presentation of turbulence modeling is provided. Some of the most common commercially available computer codes are listed. Ways to apply CFD to heat exchangers are discussed. The paper presents results from some examples of application of CFD methods for real heat exchangers in order to demonstrate how such methods can be used in the research, development, and design of heat transfer equipment. Limitations and shortcomings as well as needs for further research are also highlighted.
