NEA-0853 NAUA-MOD5.

1. NAME OR DESIGNATION OF PROGRAM:  NAUA-MOD5

3. DESCRIPTION OF PROGRAM OR FUNCTION

NAUA-MOD5 and NAUA-MOD5/M calculate the behaviour of a polydisperse aerosol system in a closed container. This container can be subdivided into a number of subcompartments geometrically separated but coupled by gas flows. For NAUA-MOD5/M an arbitrary configuration of subcompartments and flow patterns can be treated.

4. METHOD OF SOLUTION:

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:

6. TYPICAL RUNNING TIME:

The tests included in this package were run by NEA-DB on an IBM 3090 computer. The total execution time for all the test cases for NAUA-MOD5 was about 48 CPU minutes. The test case for NAUA-MOD5/M required 24 minutes of CPU time.

The tests included in this package were run by NEA-DB on a VAX 8810 computer. The total execution time for all the test cases for NAUA-MOD5 was about 6 hours and 30 minutes. The test case  for NAUA-MOD5/M required 36 minutes of CPU time.
