【求助】如何利用ansys模拟多孔材料热传递（包括热对流和热传导）
|
|||
|
各位大侠： 如何利用ansys模拟多孔材料热传递的温升方程（包括热对流和热传导），多孔材料内部是由纤维和空气组成，在加热过程中空气是自然对流传热的。可否用ansys来模拟多孔材料的热传递的温升情况！！！ 万岁！！！ |

对于您对我求助的回答，我相信您是此领域的专家。我学习ansys热分析已经有一段时间，但是选取的单元（solide 90）和建立的模型都是连续介质，而纺织材料实际上是多孔材料，在瞬态条件下热传导和热对流共同存在的。众所周知，ansys模拟问题分为三大步：1，前处理，建立模型和划分王洲；2，施加载荷；3，后处理，分析结果。您提的宝贵意见是针对第二步的，我现在首先对于选取什么样的单元（element）和建立什么样的模型还是不了解的。 希望您能够指明第一步，选取什么样的单元和建立合适的模型。 非常感谢！ |
