Analysis of Radiation Performance for a Combustion-End Radiator of a TPV System

Abstract:

In this paper, the authors analyzed effects of the factors, such as the air mass flow rate, the geometric dimensioning of the inner and outer combustion tubes and the thickness of the radiator, to the performance of the combustion-end radiator system. The result shows that optimal performance will be achieved when the combustion power is 1kW and the air mass flow rate is 5 times higher than the requirement for the complete combustion of CH₄. On this basis, the effect of the geometric dimensioning to the combustion-radiator system is discussed. The performance of the combustion-radiator system is the best when the inner diameter of inner tube is 24mm, the length of the combustion tube is 40mm and the radiator thickness is 1mm. In this condition, the average temperature of the radiant surface, the radiant power density of the radiator and the combustion efficiency are 1530K, 9.41W/cm² and 47.3%, respectively.
