基于碟式太阳能发电的β型斯特林发动机热性能数值计算
Numerical analysis for thermal performance of β-type Stirling engine based on dish solar generation
摘要
Abstract
Based on the Schmidt theory model, the relationship between a GPU-3 Stirling engine influence factors and engine thermal performance index was analyzed, with considering the dead volume of engine, and the clearance volume of the hot chamber and the cold chamber. By calculating the phase angle a, the temperature ratio τ, the stroke volume ratio k and the dead volume ratio χ have a great influence on the engine performance. With the increase of a, the engine output power N increases first and then decreases, and it is found that when a=80 °,the engine cycle power W iand N up to 167.24 J, 6.97 kW; With τ increases, N almost linearly decreased, so the smaller temperature ratio, the better the engine thermal performance, the best state can be achieved τ=0.245; With the increase of k and χ, the engine dimensionless power Z increase first and decreases after then increased, in the range of 0.6<k<1.6, 1.0<χ<1.6, the value of dimensionless power does not change much, which indicates that the engine cycle power is stable.关键词
