Chapter 7 - Advances in heat intensification techniques in shell and tube heat exchanger

Abstract

A heat exchanger is an energy carrier between two fluids. Heat transfer occurs due to the temperature gradient without direct contact between fluids. This chapter focuses on the advancements in Shell-and-Tube Heat Exchangers (STHXs) to achieve improved energy efficiency. Advanced heat exchangers have a higher heat transfer coefficient compared with other exchangers, and they efficiently perform heat intensification phenomena with limited space. The effective energy saving approach for STHX is an expansion amendment in Heat Exchanger Networks (HENs). A higher overall heat coefficient can be achieved by implementing modern advancements in existing heat exchangers. This will lead to heat transfer enhancements in STHXs. The amalgamation of advanced heat intensification techniques can facilitate the heat transfer rate and heat capacity of the exchanger. The objective of this chapter is to spotlight recent developments for STHXs and lead future investigations with modern techniques.
