Abstract
A flow conditioner for a steam turbine inlet includes an annular ring adapted to seat in a flange portion of an inlet in a turbine casing and a pair of wing portions extending from the annular ring in a flow direction, away from the annular ring. A related method of smoothing flow through an inlet of a steam turbine inlet casing wherein the inlet includes a circular flange and a non-circular transition portion extending between the annular flange and a main body portion of the steam turbine casing includes the steps of a) identifying surface discontinuities that disrupt flow of working fluid through the steam inlet; b) providing a flow conditioner that is shaped to conceal one or more of the surface discontinuities; and c) inserting the flow conditioner into the inlet.
