Thermodynamic analysis of chimney
Thermodynamic analysis, including energy and exergy, was applied for studying a chimney phenomenon. The mathematical model of a chimney was derived and used for evaluation of output trends responsive to change of some input parameters. It was proposed to use chimney efficiency as a measure of waste heat recovery. Also, the new component of exergy of the substance, called mechanical exergy, was used to determine the effect of terrestrial gravity field on the chimney process.
