Abstract
A bio mass Stirling cycle engine system with all necessary components is designed for 1 kW power output. The designed engine is simulated for air standard cycle analysis for thermodynamic performance evaluation. The relationship of cycle efficiency and power output with temperature ratio, initial pressure, and regenerator effectiveness is established. The effect of engine heat transfer, regenerator effectiveness, and properties of the working fluid on cycle performance is studied with the help of cycle simulation, and the optimum values of the temperature ratio and regeneration effectiveness are obtained. The designed and simulated engine is constructed with all necessary components and tested for validation of simulation results. The engine cycle efficiencies attained in this simulation is from 54% to 38% for corresponding regeneration effectiveness from 1 to 0.6. The temperature ratio 0.25 has shown best engine thermal performance. The results of experimentation show close association with simulation results. The results obtained by the simulation will be useful in selection of temperature range and proper working fluid for Stirling engine and will provide helpful guideline to design Stirling engine components.
