The initial application of thermodynamics to mechanical heat engines was quickly extended to the study of chemical compounds and chemical reactions. Chemical thermodynamics studies the nature of the role of entropy in the process of chemical reactions and has provided the bulk of expansion and knowledge of the field.
Thermal engineering may be practiced by mechanical engineers and chemical engineers. One or more of the following disciplines may be involved in solving a particular thermal engineering problem: thermodynamics, fluid mechanics, heat transfer, or mass transfer. One branch of knowledge used frequently in thermal engineering is that of thermofluids.
Acoustical engineering is one of many other sub-disciplines of mechanical engineering and is the application of acoustics. Acoustical engineering is the study of Sound and Vibration. These engineers work effectively to reduce noise pollution in mechanical devices and in buildings by soundproofing or removing sources of unwanted noise. The study ...
Transport phenomena are ubiquitous throughout the engineering disciplines. Some of the most common examples of transport analysis in engineering are seen in the fields of process, chemical, biological, [ 1 ] and mechanical engineering, but the subject is a fundamental component of the curriculum in all disciplines involved in any way with fluid ...
Thermofluids [1] [2] is a branch of science and engineering encompassing four intersecting fields: . Heat transfer; Thermodynamics; Fluid mechanics; Combustion; The term is a combination of "thermo", referring to heat, and "fluids", which refers to liquids, gases and vapors.
Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. Chemical thermodynamics involves not only laboratory measurements of various thermodynamic properties, but also the application of mathematical methods to the ...
However, in most engineering applications, developing a model that would be able to predict the thermodynamic properties of the system in different phases, critical regions and taking into account the possible reaction between systems is a necessity. [16]
For many non-equilibrium thermodynamical problems, an approximately defined quantity called 'time rate of entropy production' is very useful. Non-equilibrium thermodynamics is mostly beyond the scope of the present article. Another kind of thermodynamic system is considered in most engineering. It takes part in a flow process.
