Goal(s)

Given the current challenges surrounding energy optimisation and thermal management more generally, a detailed understanding of heat transfer mechanisms is becoming crucial in engineering practice. Heat transfer is a ubiquitous factor in the design of vehicles, power stations, refrigerators, heat pumps, electronic devices, energy-efficient buildings, and so on.
The aim of this course is therefore to provide a foundation of knowledge and skills for solving engineering problems involving heat transfer. The main modes of heat transfer are covered:

• Conduction
• Convection
• Radiation

Heat exchangers are commonly used in a wide range of applications, from domestic heating and air-conditioning systems to chemical processing and power generation in large industrial plants. In the analysis of heat exchangers, it is generally convenient to work with the logarithmic mean temperature difference, which is an equivalent mean temperature difference between the two fluids across the entire heat exchanger. We then discuss the efficiency method, which allows us to analyse heat exchangers when the outlet temperatures of the fluids are unknown. An introduction to heat transfer involving phase change (boiling in a pot and convective boiling, convective, film and droplet condensation) provides a comprehensive understanding of flow regimes and the orders of magnitude of the associated heat transfer rates. An application to the design of a condenser allows students to apply the various tools covered, taking into account the specific characteristics of the single-phase and two-phase zones of the heat exchanger.
