利用近似解法设计旋转式回热器

Design Rotary Regenerator with Approximation Algorithms

利用零阶和一阶近似算法,分析了旋转式回热器的旋转周期,直径及高度对其有效度的影响。结果表明,回热器有效度随高度的增加而增大,随直径的增加而增大,但与旋转周期无关。当回热器的直径达120 cm,高度达80 cm时,回热器有效度的最大值分别为94.25%和96.21%。

With zero-order and first order approximation algorithms, analyzes the influence of the cycle of rotation, diameter andheight of the rotary regenerator on its effectiveness. The results show that the effectiveness of regenerator increases with theincreasing of the height, increases with the increasing of the diameter, but is unrelated to the cycle of the rotation. When thediameter of the regenerator is 120 em and the height is 80 cm, the maximum of the effectiveness of regenerator are 94.25% and96.21% respectively.
