Thermal Conductivity of Water

According to literature1 the thermal conductivity of water is 0.598 W/m·K at 20 °C. Here the limits and accuracy of the Thermtest THW-L2 thermal conductivity meter for fluids is explored by testing a selection of water samples. For calibrating the THW-L2, deionized ultra-filtered (DIUF) water is used. With a so...

Thermal Conductivity of Common Petroleum Oil Products

Petroleum products are common throughout society. They are found in homes, farms, and industry. Here we will investigate the thermal conductivity of a few such fluids found at a small farm. Samples range from volatile petrol to thick chain and bar oil. For this project, the Thermtest THW-L2 liquid thermal...

Thermal Conductivity of Dry Wood

This is a follow up post on a study we preferred in December 2018. At that time, we looked freshly cut birch wood and its thermal conductivity. You can find that post here: https://thermtest.se/thermal-conductivity-of-green-wood For the study we are using two methods, first the Transient Line Source method utilizing Thermtest’s...

Thermal Conductivity of Green Wood

Thermal Conductivity of Green Wood

In this post we will look at the thermal conductivity of green wood, more specifically birch from the Swedish west coast. Green wood has a high moisture level and is often allowed to season, or dry, before being used. With the shifting moisture levels, also the thermal transport properties of...

Thermal Conductivity Measurements on Milk

The Thermtest THW-L2 is a thermal conductivity meter based on the Transient Hot Wire method for testing the thermal conductivity of fluids. In this example milk is used to demonstrate the sensitivity of the device. Testing fluids with a THW-L2 is easy and fast. Each measurement is only ca 1 second...
