Use of Ultraacoustic Data for the Calculation of the Thermal Conductivity of Glassy Substances at High Temperatures
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OH
Pagination or Media Count:
The study of the propagation of ultrasound in glasses has led to the determination of the temperature dependence of the thermal conductivity of glassy substances in a viscous liquid state. The possibility of applying acoustic data to the calculation of thermal conductivity has been demonstrated with the aid of new theories of heat transfer this permits the calculation of thermal currents in semi-transparent media.
