Coupled Emag-Thermal Analysis
Coupled Heat transfer analysis in electromagnetic devices due to the
power losses produced by the presence of applied and induced
currents in these devices. This analysis can be carried out coupled
with steady state current flow analysis, transient magnetic field
and manetodynamic analysis. Material properties can be a function
of temperature.
Inputs:
- The inputs for the electromagnetic part follow the corresponding
analysis as described earlier
- For the thermal part:
- Linear or nonlinear/functional, isotropic or anisotropic
material properties
- Specification of the flux tangential (adiabatic), specified
temperature, convention heat loss boundary conditions
Outputs:
- Ouput from the electrical analysis is same as discussed under
corresponding sections
- From the thermal run:
- Temperature distribution at all specified
print interval (Animation of the temperature
distribution has been provided)
- Boundary heat flux rates
For the post processing, temperature
distribution at specified time intervals and
nodal response graphs for the pre-specified
nodes, are available. Also, the temperature
distributions over time can be animated.
Typical problems that can be analysed using
this analysis type are:
- Solenoids & lift magnets
- Induction furnaces
- Transformers
- Induction machines
- Synchronous machines
