3. NATURE OF PHYSICAL PROBLEM SOLVED

SCEPTIC is a program for calculating pressure drop, flow rates, heat transfer rates, and temperature in heat exchangers such as fuel elements of typical gas  or liquid cooled nuclear reactors. The effects of turbulent and heat interchange between flow passages are considered.

4. METHOD OF SOLUTION

The computation procedure amounts to a nodal of  lumped parameter type of calculation. The axial mesh size is automatically selected to assure that a prescribed accuracy of results is obtained.
