摘要
蓄热室是蓄热式高温空气燃烧系统实现余热回收和获得高温空气的关键部件。应用多孔介质模型模拟蓄热体,采用当量连续法建立蓄热室非定常流动和传热的三维模型,对采用蜂窝陶瓷蓄热体的蓄热室在蓄热过程和放热过程中流速和温度的动态分布情况进行研究。
Regenerators, which recover waste heat and provide high temperature air, are key components of the regenerative high temperature air combustion system. In this paper, a honeycomb regenerator is modeled as a porous medium and the 3D unsteady fluid flow and heat transfer in the regenerator is modeled by using an equivalent continuum method. The dynamical distribution of velocity and temperature during the heat recovery as well as the heat release has been investigated.
