【Abstract】 Mathematics model of exergy transfer in the two dimensional heat conduction was established by using heat conduction differential equation and incorporating the evaluating criterions of engineering exergy transfer, and the definition formula of exergy transfer coefficient and exergy flux density were provided. Numerical calculation was made for such a process by taking infinite length pillar with rectangular amputation as an example.更多还原
