Simulation on the Biomass Direct-Fired Stirling Engine

The theoretical analysis of the working principle of the β-type Stirling engine was carried out. According to the constraints of their mathematical model, an analysis was made through the MATLAB/Simulink simulation software, and the simulated curves are generated under the different parameters which were used to compare and research. The results show that the output power and the pressure of the cylinder change with the different pressure, temperature, swept volume and the cylinder volume, and which reflect the influencing factors of the power. The simulation gives an intuitive theoretical basis for the design and optimization of the direct-fired biomass Stirling engine, and points out the direction of the development of the biomass energy in the new period.
