Example5 Results Import (Heat Density)

General

The results obtained in the Magnetic Analysis Example 29 are imported for a fluid-thermal analysis which takes the iron loss into account.
The temperature distribution and the heat flux vectors are solved.
Unless specified in the list below, the default conditions are applied.

Model

The air is created in addition to the coil and the core of the Magnetic Analysis Example 29.

The model is a box solid body. The material is Air (000_Air). The inlet boundary condition is set to the left face and the outlet boundary condition is set to the right face.

The remaining faces (top, bottom, front, and back) are set the outer boundary condition of slip wall.

Results

First, run the solver with the magnetic analysis model. The iron loss density is shown below.

This heat is taken into account in the fluid-thermal analysis.

Run the solver wth the fluid-thermal analysis model. The temperature result is shown below.

The heat generated by the iron loss is transmitted to the air.
