Thermodynamic Performance Analysis of Stirling Engine with a Nodal Analysis Method

摘要

A nodal analysis method for thermodynamic analysis of Stirling engine is modified based on the check of mechanical loss and the temperature of the heater and cooler. A computational modeling for simulating the process of oscillating flow and heat transfer occurring in the P-40 four-cylinder double-acting Stirling engine has been developed, and the changing effects of different parameters such as the internal pressure, temperature, velocity, power and efficiency are obtained.
