Title: Article and method of forming an article

Abstract

A cooling article and method of forming a cooling article are provided. The cooling article includes a body portion separating an inner region and an outer region, an aperture in the body portion, the aperture fluidly connecting the inner region to the outer region, and a cooling feature extending away from an outer surface of the body portion. The cooling feature disturbs fluid flow in the outer region. The method of forming a cooling article includes forming a body portion defining an inner region and an outer region, forming an aperture in the body portion, the aperture fluidly connecting the inner region to the outer region, and forming a cooling feature extending away from an outer surface of the body portion. The cooling article is arranged and disposed for insertion within a hot gas path component of a turbine engine.
