【摘要】 提出了一种螺旋集热型太阳能热气流发电系统,建立了该系统的流动与传热特性数学模型。数值模拟结果表明,与西班牙太阳能热气流试验电站相比,在烟囱出口流动与传热特性参数及输出功率相同情况下,螺旋集热型太阳能热气流的集热棚半径减少了25%,占地面积减少了44%,具有较明显的经济性和商业优势。更多还原

【Abstract】 A new helical heat-collecting solar chimney power generation system is put forward and mathematical model describing the characteristics of flow and heat transfer is established in this paper.Numerical simulation results show that: compared with the Spanish solar chimney prototype model,with the same chimney outlet parameters of flow and heat transfer characteristics and output power,the collector radius and the corresponding area of the helical heat-collecting solar chimney power generation system will decreases by 25% and 44%,respectively,which indicate remarkable economic and commercial advantages.更多还原
