SHORT REVIEW ON PERFORMANCE ENHANCEMENT OF SHELL AND TUBE HEAT EXCHANGER

Mechanical Engineering

A heat exchanger is a promising thermal device in which heat is transferred between hot and cold fluids. Researchers focused on indirect contact type compact heat exchangers among various classifications of warmth exchangers. Among these, the shell and tube device is a fluid-to-fluid heat transfer device. Shell and tube device feed devices are commonly used in process industries, refineries, chemical plants, and power plants. The analysis of shell and tube heat exchangers is typically divided into two parts: shell side analysis and tube side analysis. Shell side analysis is simple and requires little modification. The tube side analysis is more complex, and it is accomplished by varying baffle design and elevation in relation to arrangements. The most significant disadvantage of the shell and tube device is the pressure drop that occurs at the ends of the tubes that may affect the heat transfer efficiency. Researches on enhancing the heat transfer through shell and heat exchanger by optimization of parameters is in recent trends now-a-days. This paper focuses on reviewing literatures on enhancement of heat transfer rate of shell and tube heat exchanger.
