Abstract
A numerical analysis has been carried out of the stability and thermal performance of internally cooled superconductors. The analysis of the system in question was performed using a one-dimensional computer code developed by Arp 1 based on a program for non-linear partial differential equations developed by Sinovec 2 and slightly modified by the present author. The effects of helium mass flow rate and hydraulic perimeter on the stability margin have been studied. The computer simulation results are presented in this paper. These results indicate that the thermally induced pressure gradients and fluid velocity caused by rapid perturbations are responsible for the stability margin, and both mass flow rate and hydraulic perimeter are quite significant factors for achieving high stability margins. A forced flow cooled superconductor with dual composite cooling channels is suggested from these results.
