WebIf these two things are true, we know that the heat for system B will be Q B = C ( T A − T B) and consequently by conservation of energy if system B has only thermal contact with the working substance, the heat input is Q = C ( T B − T A). The first fact is obvious. In thermodynamics and engineering, a heat engine is a system that converts heat to usable energy, particularly mechanical energy, which can then be used to do mechanical work. While originally conceived in the context of mechanical energy, the concept of the heat engine has been applied to various other kinds … Ver más In thermodynamics, heat engines are often modeled using a standard engineering model such as the Otto cycle. The theoretical model can be refined and augmented with actual data from an operating engine, … Ver más It is important to note that although some cycles have a typical combustion location (internal or external), they often can be implemented with the other. For example, John Ericsson developed … Ver más Heat engines have been known since antiquity but were only made into useful devices at the time of the industrial revolution in the 18th century.
