Coil pulse heating

coil transient current, solenoid switching on, transient current in solenoid, multiphysics analysis

A single triangle-shaped voltage pulse is applied to the coil.

Problem Type:
Axisymmetric multiphysics problem of Transient magnetics coupled to Transient heat transfer.

Geometry:
Coil pulse heating A single triangle-shaped voltage pulse is applied to the coil Core Winding 300 mm D 40 mm D 100 mm

Given:
Number of turns N = 275;
Magnetic permeability of steel μ=1000;
Voltage pulse magnitude U = 100 V, pulse duration - 0.5 s.
Initial temperature T0 = +20°C

Task:
Calculate the switching current, heating power and temperature rise.

Solution:
Analysis requires combined electromagnetic and heat transfer simulation. First the transient magnetic problem is simulated and current and Joule heat power are calculated at every moment of time. Then transient heat-transfer problem is simulated. Heat transfer problem takes the Joule heat power momentary values from the transient magnetic problem results.

Result:
Voltage and current vs. time plot:
Coil switching current vs. time plot

Power and average temperature vs. time plot. Winding temperature rise is ΔT = 4°C.
