A numerical analysis of the thermal stability of a superconductor composite cooled by forced-flow supercritical helium has been performed. The analytical model consists of simultaneous two-dimensional coolant flow equations and a one-dimensional superconductor equation. The equations of conservation of mass, momentum and energy for coolant flow and the Fourier heat conduction equation for the superconductor were solved numerically. Current-sharing mode, temperature-dependent properties of the conductor, and pressure- and temperature-dependent coolant properties were fully taken into account. The transient behaviour of the conductor, coolant flow, the effects of disturbance-heated length of the conductor, the initial pressure and initial velocity of coolant on the thermal stability of superconductors are discussed.
