3. NATURE OF PHYSICAL PROBLEM SOLVED
This program calculates transient temperatures in a concentric, cylindrical configuration. Up to 25 concentric regions are allowed, each containing either a stationary (solid or non-flowing liquid) or turbulently flowing (liquid or gas) material. Any stationary region can have spatial- and time-dependent heat generation. Temperatures are calculated at node points equally- spaced within a region.
Film coefficients on flowing region boundaries are calculated by the program. Time-dependent coolant velocities are permitted.
The heat source is assumed to be angular independent. Axial heat conduction is neglected, but axial heat transport due to material motion is considered in the flowing regions.

4. METHOD OF SOLUTION
Temperatures are calculated at each node point at discrete time intervals using finite difference methods.
Second order polynomials are used to approximate the temperature dependence of the properties of the flowing materials. The thermal properties of stationary materials are considered constant within a temperature phase. There may be up to 9 phase changes, with heats of transformation added to the material at the transformation temperatures. Thermal resistances at stationary region interfaces are considered by means of input coefficients of heat transfer.

7. UNUSUAL FEATURES OF THE PROGRAM
Essentially complete flexibility in the shape of the heat generation function is provided through pointwise specification of its spatial-time-dependent components. The time dependence of the flowing material velocities is specified pointwise, also. Similarly, the equations for calculating the film coefficients on flowing material boundaries were chosen to accommodate a wide variety of needs. Cooling, as well as heating, of stationary materials through phase transformations is allowed. Once the temperature of a flowing material reaches the saturation point, however, it is held there, and no cooling is allowed.

14. ANY OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS
The CDC3600 source version of this code should be compatible with other machines, subject to monitor restrictions, of course, except that the common and equivalence statements should be checked to insure that the variable Y (=TDT) precedes all others in common storage assignment.
