Heat transfer to throat tubes in a square-chambered rocket engine at the NASA Lewis Research Center [PDF]

open access: yes
A gaseous H2/O2 rocket engine was constructed at the NASA-Lewis to provide a high heat flux source representative of the heat flux to the blades in the high pressure fuel turbopump (HPFTP) during startup of the space shuttle main engines.

Effect of heat flux on pitting and passive film of 304SS in 3.5 wt.% NaCl solution

open access: yesnpj Materials Degradation
In this work, the effect of heat flux on pitting corrosion behaviors and passive film properties of 304 stainless steel in 3.5 wt.% NaCl solution were investigated by the self-developed metal heat transfer surface testing system using electrochemical ...

On the conjugate interface conditions and Galilean invariance [PDF]

open access: yesarXiv
In the referred paper("H. Karani, C. Huber, Physical Review E, 91(2)(2015) 023304"), a total heat flux continuity condition for conjugate heat transfer problems with moving interfaces was proposed. The authors asserted both conductive and advective heat fluxes are conserved simultaneously in their formulation.

Numerical Studies of Influencing Factors on the Homogeneity of the Powder Mixture during the Powder Spreading Process of Powder Bed Fusion–Laser Beam/Metal

open access: yesAdvanced Engineering Materials, EarlyView.
AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by
