Thermal machines ================ A **thermal machine** is a device that permits energy conversion. It consists generally in a set of components such as compressors, turbines, combustion chambers, pumps, heat exchangers, valves, etc. Components of a thermal machine may be crossed by a working fluid (gas or liquid) and then represent open subsystems that can exchange heat and work. A thermal machine may be: * A heat engine: it converts thermal energy to produce a mechanical work. * A refrigerator or a heat pump: it uses a mechanical work to transfer thermal energy from a source to a sink. This course presents the basics requisities for an engineer to understand, study and developp *thermal machines*. It is dedicated to engineer student with a background in thermodynamics for closed systems and basics of fluid mechanics. The course contains 5 chapters: * The first section is a recall of thermodynamics and introduction to fluid mechanics courses. Balance equations are recalled and applied to a control volume representing a component of a thermal machine. * The second section presents the basics of energy conversion using thermal machines as well as reference thermodynamics cycles. * The third section is devoted to the specific notion of compression/expansion of a gas and how to optimize these thermodynamics transformations. * The fourth section is describing classical heat engines: internal reciprocating heat engines, gas turbines and steam turbines. * The fifth section is devoted to heat pumps and refrigerators. .. toctree:: :maxdepth: 2 :caption: Contents: :numbered: chap1_balanceEquations_Chap chap2_thermMachinesBasics_Chap chap3_CompExpGas_Chap chap4_ThermalEngines_Chap chap5_ThermalGenerators_Chap zBibliography Table of contents ================= * :ref:`genindex` * :ref:`search`
