Thermal fluids or Thermofluids〔http://mech.ubc.ca/undergraduate-students/thermofluids/〕〔http://www.imeche.org/knowledge/industries/thermofluids〕 is a branch of science and engineering divided into four sections: *Heat transfer *Thermodynamics *Fluid mechanics *Combustion The term consists of two words: "thermal", meaning heat, and "fluids", which refers to liquids, gases and vapors. Pressure, volume, and density all play an important role in thermal fluids. Temperature, flow rate, phase transition and chemical reactions may also be important in a thermal fluids context. ==Heat Transfer== Heat transfer is a discipline of thermal engineering that concerns the transfer of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase-change transfer. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer. Sections include : *Energy transfer by heat, work and mass *Laws of thermodynamics *Entropy *Refrigeration Techniques *Properties and nature of pure substances 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「thermal fluids」の詳細全文を読む スポンサード リンク
