摘要

This paper presents experimental results of the thermal contact conductance between a solid surface and a zeolite powder. For the measurements the laserflash method was modified. The advantage of this method is that the sample is heated by a laser pulse without contact and the temperature is measured by a pyrometer also without contact. Measurements of the thermal contact conductance were carried out in the pressure range of 0.0015 bar < p < 30 bar with the filling gases hydrogen, nitrogen and argon. The thermal contact conductance between a copper plate lying on top of the zeolite powder and the zeolite powder varies between 3 W/m~2K and 423 W/m~2K.
