Numerical solutions of the one-dimensional conservation equations of fluid flow are given for the problem of the cool-down of superconducting power transmission cables. By including the continuity and momentum conservation equations, both time dependent and spatially dependent mass flow may be treat

โฆ Synopsis
A system of equations, describing the refrigerant's parameters (temperature and pressure) change, during its flow along a heated pipeline, for example along a superconducting power transmission line (SPTL), is derived.
The possibility of a temperature maximum existing in the SPTL is found.
The possibility, in principle, of "isothermal" SPTL (with constant temperature, along its length) is shown. The most favourable refrigerant parameters" region for SPTL is determined.
