Conventional methods for enhancing heat transfer relevant to heat exchangers

Abstract

The enhancement of heat transfer is an essential component of thermal engineering. It plays a key role in enhancing the efficiency and performance of heat exchangers across a wide range of industries, including manufacturing and energy production, among others. A complete examination of numerous tactics aimed at maximizing heat transmission is presented in this chapter. These strategies are divided into three primary approaches: passive methods, active methods, and hybrid-based approaches. In this chapter, we investigate the application of these methodologies across various types of heat exchangers, including shell and tube, plate, air-cooled, and microchannel systems. We also emphasize the specific problems and performance outcomes that are associated with each design. The chapter goes into many approaches to evaluate the efficiency of heat transfer, including experimental, analytical, and numerical methods, and provides a comprehensive understanding of the advantages and disadvantages of each of these methods. In addition to providing ways for performance improvement, this chapter also discusses the difficulties and limitations connected with the implementation of heat transfer enhancement solutions. The purpose of this chapter is to provide engineers and researchers with the information they need to make educated judgments regarding the optimization of heat exchanger systems. This will be accomplished by providing insights into the practical aspects of adopting them. A synthesis of the most important discoveries is presented at the end of the chapter, which also identifies crucial research gaps and provides prospective areas for future work in the topic of heat transfer enhancement.
