  • Sample holder assembly for effective thermal conductivity measurement of pebble-bed in laser flash apparatus
    Patent number: 10928338
    Abstract: The present disclosure provides a sample holder assembly for a laser flash apparatus for measuring a thermal conductivity of a pebble-bed, the assembly comprising: a tubular sample container configured to be mounted on a sample carrier tube for the laser flash apparatus, wherein the sample container has open top and bottom; a bottom disc disposed in the sample container to block the open bottom of the sample container and configured for delivering a laser from a laser flash unit of the apparatus to a pebble-bed; the pebble-bed packed on the bottom disc to a predetermined thickness; and a top disc disposed on the pebble-bed and in the sample container to block the open top of the sample container and configured for receiving heat from the pebble-bed to transfer the heat upward.
