Computer simulation of thermal process during quench in superconducting winding of solenoid

A precise computer code was developed to model nonstationary 3D thermal processes, in particular during quench, in an adiabatic solenoidal winding of a superconducting magnet. The code solves, with desired precision, the set of 1D nonlinear nonstationary heat balance equations, each of which treats, in a section of winding, dynamically interdependent processes of heat propagation along a helix-shaped wire and transverse heat transfer across interturn insulation. For a fixed current, a dimensionless analysis of normal zone propagation within a single solenoid layer was carried out with the code to demonstrate the peculiar influence of the wire helicity on longitudinal and transverse velocities of the normal zone and the layer temperature profile.<>
