A heat exchanger, as its name suggests, is a component that transfers heat between two fluids separated by a solid wall. The process of exchanging heat between different fluids is one of the most important and frequently encountered processes found in engineering practice, for example, boilers, condensers, water heaters, flue gases heaters. In some components, heat exchange is associated with a phase change of one of the fluids such as condensation or evaporation. This chapter presents the different heat exchanger design methods (LMTD, NTU, UA, and efficiency method) and the different correlations utilized to compute the convective heat transfer coefficient for single- and two-phase flow (evaporation and condensation). Then, models are presented for various types of heat exchangers: shell and tube, dynamic two-phase flow pipe, dynamic single-phase flow shell, water- or gas-wall, dynamic and static water heating, dynamic and static condensers, dynamic and static plate heat exchangers, and flue gases heat exchangers. A detailed description of the physical equations is given for each component model: modeling assumptions, fundamental equations, and correlations with their validity domains. A test-case is provided for each component model that includes the structure of the model, the parameterization data, the simulation results, the model validation, and in some cases the experimental validation. It is a valuable aid to understand the physical phenomena that govern the operation of power plants and energy processes. It is a main and full support to develop models for industrial power plants. The full description of the physical equations is independent of the programming languages and tools.
