Abstract
Shell and tube heat exchangers (STHE) are widely used in chemical, power, and process industries due to their robustness and efficient heat transfer. This study focuses on optimizing the design parameters of STHE to improve thermal performance and reduce manufacturing cost while maintaining operational reliability. Using traditional design principles, parametric analysis was conducted on key variables such as baffle spacing, tube diameter, and shell diameter. A combination of empirical correlations and simulation methods were employed for heat transfer and pressure drop calculations. Statistical analysis identifies the most influential parameters impacting performance. The study concludes with optimized design guidelines enhancing heat exchanger efficiency within the constraints of 2019 technology.
