Louver And Effusion Cooling Heat Transfer For A Double Wall Effusion Plate With Impingement Jet Array Coolant Supply, Sneha Reddy Vanga, Phillip M. Ligrani, Joseph Knox, Federico Liberatore, Rajeshriben Patel, Ying-Hsiang Ho Apr 2021

Louver And Effusion Cooling Heat Transfer For A Double Wall Effusion Plate With Impingement Jet Array Coolant Supply, Sneha Reddy Vanga, Phillip M. Ligrani, Joseph Knox, Federico Liberatore, Rajeshriben Patel, Ying-Hsiang Ho

PRC-Affiliated Research

Louver slot cooling is employed, which consists of an aligned collection of film cooling holes, contained within a specially-designed device which concentrates, and directs the coolant from a slot, so that cooling air then advects as a layer downstream along the test surface. This louver-supplied coolant is then supplemented by coolant which emerges from different rows of downstream film cooling holes. Coolant for both cooling arrangements is supplied using an array of impingement jets. Experimental data are provided for a mainstream Reynolds number Rems range of 168,000–181,000. Full-coverage film cooling initial blowing ratio values are 2.5, 3.2, 4.4, and 5.2, …

On The Influence Of Heat Treatment On Microstructure And Mechanical Behavior Of Laser Powder Bed Fused Inconel 718, Jakob Shroder, Tatiana Mishurova, Tobias Fritsch, Itziar Serrano-Munoz, Alexander Evans, Maximilian Sprengel, Maximilian Sprengel, Manuela Klaus, Giovanni Bruno Feb 2021

On The Influence Of Heat Treatment On Microstructure And Mechanical Behavior Of Laser Powder Bed Fused Inconel 718, Jakob Shroder, Tatiana Mishurova, Tobias Fritsch, Itziar Serrano-Munoz, Alexander Evans, Maximilian Sprengel, Maximilian Sprengel, Manuela Klaus, Giovanni Bruno

PRC-Affiliated Research

A range of heat treatments have been developed for wrought Inconel 718 to obtain desired properties. For additively manufactured Inconel 718, the recently developed standard ASTM F3301 provides guidance for heat treatment of powder bed fusion specimens. Although this standard is based on standards developed for wrought Inconel 718, it does not include direct aging. Since direct aging reduces the number of processing steps, it can result in a post processing cost reduction if the desired properties are obtained. In this study, we characterized the microstructure and tensile behavior of Inconel 718 specimens produced by a laser powder bed fusion …
