matlab潮流计算含代码密集颗粒传热 该代码使用基于离散元素方法(DEM)的模型来计算在细小颗粒状流中通过类似沙子的小颗粒组的热传递。 它是为粒子热交换器和固体粒子太阳能接收器开发的,但对于类似主题的研究也可能有用,例如石灰窑,粉末床的激光烧结或冶金Craft.io。 其他研究人员已经为自己的研究开发了类似的代码,但是这些代码尚未公开。 可以在可用的DEM代码(例如开源代码LIGGGHTS或其他商业代码)内完成某些热传递建模,但是这些DEM代码不包括几种关键的热传递模式。 DPHT是用于大组球形小颗粒的热传递代码,球形小颗粒呈致密颗粒状流动或呈静态。 首先使用DEM模拟粒子碰撞机理,然后随着时间的推移将粒子xyz位置写入文本文件。 完成DEM模拟后,此DPHT代码将读取每个xyz位置文件,并计算粒子之间以及粒子与壁之间的热传递。 这可以被认为是与DEM的单向耦合。 DPHT是为在聚光太阳能领域中的固体颗粒太阳能接收器和热交换器建模而开发的,但是它适用于具有堆积或移动颗粒床的许多情况。 传热计算是基于先前发表的研究工作,论文对此进行了解释: 聚光太阳能领域高温粒子流建模的研究进展,埃文
