The book "Design and Analysis of Shell and Tube Type Heat Exchanger" by Kevin Shah offers a comprehensive examination of heat exchangers, particularly shell-and-tube heat exchangers, which are widely used in various industries. It explains how these devices are utilized for energy savings and improving efficiency in applications such as plastic processing. The book discusses various design options and the optimization of heat transfer capacity to identify the best parameter combinations for enhancing efficiency. By applying the Taguchi method and conducting CFX analyses in ANSYS, different models are developed to determine the optimal dimensions for minimizing the water temperature at the outlet. This detailed analysis is of great value to professionals and students in the fields of engineering and IT.
