Overview

This course provides a comprehensive study of the design, analysis, and selection of heat exchangers-critical components in thermal systems across diverse industries such as power generation, chemical processing, aerospace, energy, and HVAC.Designed for mechanical engineering students and professionals in allied fields like chemical, aerospace, and energy engineering, the course emphasizes both theoretical foundations and practical applications. Students will explore the classification and working principles of various heat exchanger types, selection criteria, performance evaluation, and detailed thermal and hydraulic design methodologies.Topics include recuperative and regenerative heat exchangers, flow arrangements, the LMTD and ε-NTU methods, pressure drop analysis, forced convection correlations, and advanced considerations like micro/nano heat transfer and fouling. Special attention is given to double-pipe heat exchanger design and operational optimization.By the end of the course, participants will possess the knowledge and analytical tools to efficiently design and evaluate heat exchangers tailored to specific applications.Course Topics:1.
