| Abstract: | Using the general theory of thermodynamics,we deduced the expressions of thermodynamic functions of Van der Waals gas,and calculated the expressions of work and heat in the adiabatic process and three kinds of equivalent process.Based on that,we studied the work and efficiencies of Stirling cycle,Otto cycle,and Diesel cycle.Relationships between the three kinds of cycle efficiency and the change of various parameters were calculated and analyzed. |
