Module 7
Thermal Management and Cooling
1
Heat Diffusion in Joule-Heated Conductors
Derive the heat diffusion equation for a conductor with internal Joule heating to model temperature evolution.
2
Conductor Temperature Dynamics: Current Pulse & Heat Diffusion
Apply the heat diffusion equation to calculate the temperature profile in a conductor during and after a current pulse.
3
Thermal Diffusion Length and Heating Regimes
Estimate the thermal diffusion length to determine whether heating is adiabatic or quasi-steady for different pulse durations.
Cooling Systems: Forced Water vs. Liquid Nitrogen
Compare forced water and liquid nitrogen cooling systems, evaluating their respective heat transfer capabilities and operational constraints.
Magnet Coil Heat Load Calculation
Calculate the total heat load generated in a magnet coil during a single pulse and over a series of pulses.
Coolant Flow Rate for Temperature Control
Calculate the required coolant flow rate to maintain a target conductor temperature for a given repetition rate.
Thermal and Electromagnetic Stress Analysis
Analyze thermal stress resulting from non-uniform heating and its superposition with electromagnetic stresses.
8
Thermal Equilibrium in Pulsed Magnets
Calculate the thermal equilibrium temperature in a repetitively pulsed magnet by balancing Joule heating with inter-pulse cooling.
