| 摘 要： | 本文对10kW电热固体蓄热装置的蓄热过程进行了数值模拟，在将蓄热固体颗粒和粒子间的空气看作均相介质的假设基础上，建立了蓄热过程中蓄热体内径向传热模型，根据初始条件和边界条件进行了数值计算，分析了误差产生可能原因，并利用有效导热系数分析了数值解和实验结果之间的误差。

| Abstract: | In this paper,electric heat solid heat storage device of 10 kW heat storage process was simulated.Radial heat transfer model of the device during heat storage was built on an assumption that solid heat storage granules and air between the granules were regarded as homogeneous media and numerical calculation of the model was made according to original and boundary conditions of the model.Error analysis was done and effective conduction coefficient was used for analyzing errors between numerical values soluti... |
