Аннотация

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 behaviors 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 superconductor will also be discussed.
