Additive manufactured flow components with stress-resistant structures

Abstract:

This disclosure provides flow components, methods of additive manufacture, and output manifolds for heat recovery steam generators incorporating flow components. A flow component may include an annular wall that defines a flow path for a fluid. The annular wall may have a normative region and a stress region. The annular wall in the stress region may include a continuous skin to form a portion of the interior wall surface and an additive manufactured mesh adjacent to the continuous skin to the interior of the annular wall. The annular wall in the normative region may have a cross-section with a different structure than the stress region.
