Description

This course provides a comprehensive introduction to the principles and applications of heat transfer, focusing on the fundamental mechanisms of conduction, convection, and radiation. Designed for students aiming to pursue careers in engineering, energy, and related fields, the course offers a solid understanding of both theoretical concepts and practical problem-solving techniques.The course begins with an exploration of the basic modes of heat transfer and the underlying physical principles. Students will develop a deep understanding of conduction through Fourier’s law, learning to analyze steady-state and transient heat conduction in one-dimensional and multi-dimensional systems (Cartesian, cylindrical and spherical coordinates). Further, concept of critical radius of insulation also explored in case of conduction phenomenon.  The study of convection covers forced and free convection, the boundary layer concept, and the use of dimensionless numbers like Reynolds and Prandtl numbers to characterize fluid flow and heat transfer. The course also delves into radiation heat transfer, emphasizing the Stefan-Boltzmann law, view factors, and radiative heat exchange between surfaces.A significant portion of the course is dedicated to the analysis and design of heat exchangers, where students will learn about various types of heat exchangers, performance evaluation methods, and the impact of fouling and correction factor. The course includes a strong emphasis on numerical methods, using mathematical models and computational techniques to solve real-world heat transfer problems.Practical applications are reinforced through a series of numerical problems designed to enhance students’ analytical and problem-solving skills. By the end of the course, students will be equipped to approach complex heat transfer problems, conduct thermal analysis, and apply their knowledge in engineering and industrial applications.
