FEA Model
ANSYS FEA Model of Feedwater Heater

 

O’Donnell Consulting performed FEA and ASME Code Section VIII Division 2 calculations on feedwater heaters.
In modelling the heaters, the assumptions included:
• Linear elastic material behavior with small displacements
• The geometry, loading and boundary conditions consistently have one plane of symmetry down the axis of the vessel. Then analyses were completed on a half model of the heater with symmetry boundary conditions applied on the cut boundary. The nozzle was treated as having half symmetry.
• A reduced set of U-tubes was modelled. Properties of the modeled tubes were adjusted to account for the not-modeled tubes.
