Thermal Conductivity Test

Thermal conductivity is an ability of material to transmit heat and it is measured in watts per meter kelvin of surface area for a temperature gradient of 1k per unit thickness of 1m.

Thermal conductivity test.

Thermal conductivity differs with each substance and may depend on structure density humidity pressure and temperature. Thermal conductivity is a measure of a materials ability to transfer heat most often denoted as k or k value. What is thermal conductivity testing. Basalt ridge testing laboratory llc is equipped to characterize the thermal conductivity of many fluids including water based nano fluids.

This new technique is based on multi dimensional model based trt data analysis. Thermtest has been measuring thermal conductivity thermal diffusivity thermal resistance and specific heat for more than a decade. If you are not sure of the test method to be used please contact us with your sample information or read the samples section below. Thermal conductivity is a fundamental material property associated with the ease with which heat energy is conducted through a specific material.

The thermal conductivity of a material is a measure of its ability to conduct heat it is commonly denoted by or. Time thickness of the sample thermal conduction constant and temperature of the test are all taken into account when solving for thermal conductivity. Our measurement technique is limited to fluids as viscous as or more viscous than water at 40 c. Q t kat d.

Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity. Sample temperature control is available upon request. This test provides the engineer with valuable information about the earth s thermal properties which are necessary to size the ground heat exchanger ghx. Write down the equation for thermal conductivity.

In order to measure thermal conductivity you need to account for all variables that could affect heat loss or gain. For thermal conductivity testing the selection of test method is dependent on the sample type. The doe is now validating a new advanced thermal conductivity test said to require half the time as the existing approach while also eliminating the requirement for a stable thermal source.
