1. NAME AND TITLE
WAKE: Navier Stokes Equation with 2-D Turbulence, Stream Function, Vorticity.
through the OECD Nuclear Energy Agency Data
Bank, Issy-les-Moulineaux, France.
3. CODING LANGUAGE AND COMPUTER
Fortran, IBM 370 Series (P00605I037000).
4. NATURE OF PROBLEM SOLVED
WAKE solves the turbulent Navier Stokes equations using a two equations model of turbulence (kinetic energy and dissipation rate) and stream function, vorticity representation of the mean flow pattern. Much of input is specified by coding in various subroutines - a detailed knowledge of the function and operation of each subroutine is necessary before the user can confidently set up his/her own problem.
5. METHOD OF SOLUTION
Finite difference solution of flux equation in an orthogonal mesh specified by the user.
6. RESTRICTIONS OR LIMITATIONS
Model size is defined by array sizes set in FORTRAN routines.
7. TYPICAL RUNNING TIME
Problem set up at present is of the order of 15 minutes CPU time.
8. COMPUTER HARDWARE REQUIREMENTS
IBM 370. (More than 200 k bytes of fast core, card reader, line printer, and if restart and dump facility used two magnetic tape units. Code uses clock facilities to prevent over-running allocated time.)
9. COMPUTER SOFTWARE REQUIREMENTS
ICL RIOS, IBM OS 370/OS.
