Abstract
Liner structure for a duct carrying a heated fluid is described which comprises a substantially cylindrically shaped wall member having a corrugated inner surface contour defining a first plurality of axially extending ridges defined between a corresponding plurality of axial grooves, a second plurality of axially spaced vee-shaped vanes disposed on each ridge with the legs of each vane divergent toward the downstream end of the duct, an elongated cap disposed along each ridge atop corresponding vanes and defining a corresponding plurality of slots between each cap and ridge, and a third plurality of holes through the wall member at each ridge between axially adjacent vanes for conducting fluid coolant through the wall member.
