Heat Flux From Flames to Vertical Surfaces

January 1, 1994
Author(s)
J. G. Quintiere, Thomas Cleary
Dimensional analysis is used to examine heat transfer from flames to vertical surfaces. Configurations include a line fire against a wall, a square burner flame against a wall and in a corner, and window flames impinging on a wall. Dimensionless parameters

Hertzian Contact Resonances

January 1, 1994
Author(s)
John A. Kramar, T Mcwaid, J Schneir, E C. Teague
The resonant frequency of a sphere in contact with a flat surface was measured as a function of loading force for contacting materials with different elastic moduli. Comparisons were made with predictions based on the Hertzian theory of elastic deformation

Hot Electron Spin-Valve Effect in Coupled Magnetic Layers

January 1, 1994
Author(s)
Robert Celotta, John Unguris, Daniel T. Pierce
SEMPA observations of magnetic exchange coupling in the Fe/Ag/Fe, Fe/Au/Fe, and Fe/Cr/Fe systems reveal an intensity variation in the emitted secondary electron signal that depends only on whether the Fe layers are coupled in a ferromagnetic or
