Capabilities
| Rating (Performance Analysis) |
| Calculation of Q, U,
and outlet temperatures
Calculation of heat transfer surface
Calculation of core height, core width (for a
specified heat load)
Calculation of flow rates (for a specified heat
load) |
|
Preliminary Design Sizing
| With respect to core
height, width, and flow rates or a combination of
these variables |
|
Optimization
| With respect to core
height, width, and flow rates or a combination of
these variables. The program evaluates all viable
configurations within the limits that you provide
to arrive at a number of feasible solutions listed
in the order in which they satisfy an optimization
criterion. Criteria include minimum pressure drop,
minimum heat transfer surface area, minimum power,
or a combination of these. |
