3.
DESCRIPTION OF PROBLEM OR FUNCTION - Bulk flow distribution in a cylindrical reactor coolant inlet plenum is calculated using potential flow theory.
4.
METHOD OF SOLUTION - The Laplace equation for the velocity potential is solved for general, symmetric boundary conditions and one inlet nozzle by Gauss-Seidel relaxation (part 1). Nonsymmetric, dimensional solutions are then formed by superposition of the general solution (part 2).
5.
RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - The code is dimensioned for 8000 mesh points in an (r,theta,z) array. Dimensions can be expanded at the expense of run time and core size.
6.
TYPICAL RUNNING TIME - Run time for part 1 is proportional to n**2, where n is the number of mesh points. With 2299 mesh points CPU time is 42 seconds on a 360/195. Run time for part 2 is 1 second per problem. Sample problem running time is 2 minutes for part 1 and 1 minute for part 2.
7.
UNUSUAL FEATURES OF THE PROGRAM - The code approximates bulk fluid motion through large cylindrical headers in circumstances where details of the flow, such as boundary layer effects, may be neglected. Three-dimensional effects are calculated, so that asymmetric fluid input and output problems may be calculated. Use of a linear field equation permits rapid solution by superposition of many combinations of input and output boundary conditions. First order effects of friction may be included by addition of constant coefficients in the finite difference formulations.

MACHINE REQUIREMENTS - 240K bytes of storage and an on-line punch and printer. 12.
PROGRAMMING LANGUAGE(S) USED - 13.
OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED - OS/360. 14.
OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS - PLENUM is written as two separate programs. Part 1 provides a general dimensionless solution to the field equation. For a given header this code need only be executed once. Part 2 uses punched output from part 1 to determine solutions for a variety of user-specified boundary conditions by dimensionalization and superposition.
