Abstract: A quasisteady method for measuring the thermal diffusivity of molten salts at temperatures above their melting point is described. Essentially, the difference between the temperature at the surface ...

Abstract: Thermal transpiration, the phenomenon of the flow of gases through porous media under the influence of a temperature gradient, can be utilized as a driving force in a new type of gas pump. ...

Abstract: This paper describes a method for the determination of thermal diffusivities which has been developed specifically for substances which are poor conductors and which have high melting points. ...
