Thermal efficiency

In thermodynamics, the thermal efficiency (\eta_{th} \,) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, a steam turbine or a steam engine, a boiler, a furnace, or a refrigerator for example. In other words, efficiency indicates how well an energy conversion or transfer process is accomplished.
