# 感应炉模拟小技巧

2015年 3月 4日

### 利用 COMSOL Multiphysics 进行模拟

#### 传热问题

Q_{loss} = \frac{\dot m C_p (T_{in} -T)} {2 \pi r * \pi r_{int}^{2}}

#### 数值方面

\delta = \sqrt\frac {1} {\pi \cdot \mu_R \cdot \mu_0 \cdot \sigma \cdot f}

#### 电磁场将如何影响熔池行为？

F^{Lorentz} = j \times B

### 关于特约作者

Vincent Bruyere 拥有国立里昂应用科学学院颁发的机械工程学博士学位，其研究课题为润滑接触。之后，Bruyere 继续在原子能和替代能源委员会 (CEA) 进行博士后研究。现在他是 SIMTEC 的一名仿真工程师。他所开发的数值模型主要应用于流体力学、热学和电磁学应用。

hi, in your model, the four coils are seperate, what if the coil is a winding and water flows from the start to the end? How to simulate this situation?

Hello, I have also been doing simulations on the three-field coupling of the induction magnet thermal magnetic flow recently. Your article is really meaningful to me! I hope to get a .mph file from this article, as a reference for learning, thank you very much! My email: a2275022@126.com
