The performance analysis of heat transfer and heat-work conversion is very important in energy utilization. T-q diagram for heat transfer is discussed and extended to heat-work conversion processes. The results show that T-q diagram is convenient for expressing entransy dissipation and analyzing heat transfer performance and can express work entransy and entransy loss intuitively. It could have an application in analyzing the performance of heat-work conversion processes.
