中文摘要:
      填充床储能是一种很有发展前景的热能储存技术,它具有可降低存储成本和提高太阳能热系统开发效率等优点。研究人员多采用球形的储能单元,而圆柱体在储能填充床换热中有其独特的优势,因此基于圆柱形和拉西环形两种柱状颗粒,建立了一种潜热储能填充床的三维模型,采用数值模拟的方法分别研究两种柱状颗粒组成的填充床的储能性能,分析了储能填充床的直径比对其性能的影响。研究表明,填充床直径比越大,其储能性能越好。同时研究了圆柱形储能单元高度和拉西环形储能单元孔径对储能性能的影响。结果表明,在研究范围内,由高度为3 mm的圆柱形储能单元和孔半径1.50 mm的储能单元分别组成的填充床储能速率最高。
英文摘要:
      Packed bed is a promising heat storage way with the advantages of reduced storage cost and improved development efficiency of solar thermal system. The spheric energy storage unit was frequently adopted by researchers, while the cylindrical one also had some unique advantages in energy storage. Based on two column particles such as cylinder and Raschig ring, a three-dimensional packed bed model for latent heat storage was established. Their energy storage performance in the packed bed was studied by numerical simulation. Effect of the diameter ratio of bed to particle on its performance was studied. Results show that the larger the diameter ratio of bed to particle, the better the energy storage performance. Effects of cylinder height and Raschig ring pore size in the energy storage unit on energy storage performance were studied. Results show that within the investigated range, the energy storage unit in the packed bed with the cylinder height of 3 mm or pore size of 1.50 mm had the highest energy storage rate.
