Abstract

A measuring device based in thermal wave interference in a cavity is described. It was tested measuring the air thermal diffusivity with good accuracy. The device is further applied to the measurement of the thermal diffusivity of air mixed with the vapors of liquid hydrocarbons of the paraffin family (n-pentane, n-hexane and n-heptane). Our results illustrate how the diffusion of their vapors in air can be monitored by a simple method and how the thermal properties (i.e. the thermal diffusivity) of the gas mixture change as a result of this mechanism. Based in the former results a device suitable for in field measurements is predicted.
