Abstract

The purpose of this paper is to examine the characteristics of shell and tube heat exchangers and their relationship to flow direction. The second experiment is designed to elucidate the effect of temperature on heat transport and the effect of various exchange types. Calculation of overall heat transfer efficiencies is necessary to determine the most efficient condition. To achieve maximum efficiency, a higher flow rate combined with counter current flow operation should be used. Nonetheless, as the flowrate increases, the overall efficiency of the plate heat exchanger decreases significantly. The logarithmic temperature is a critical parameter in designing an efficient counter current shell-and-tube heat exchanger. The overall efficiency of the heat exchanger and the amount of heat emitted increase as the logarithmic mean temperature difference increases. Multiple factors contribute to discrepancies in results. Because stream pressure can influence operation efficiency, it is necessary to conduct a pressure analysis during operation. It is necessary to regulate the flow rate to avoid overloading the operation. Additionally, fouling deposition is a frequent cause of efficiency loss. Routine performance checks, cleaning, and maintenance all contribute to the heat exchanger's reliable operation.
