Overview In this webinar, we compare which transient method is ideal for liquid. The transient methods explored will be Hot-Wire, Line Source, and Plane Source. Our test results on (liquid type here) using the three methods will be discussed. About the Speaker Dr. Sofia Mylona is an internationally recognized expert in the area of the [...]

Overview Steady-state thermoreflectance (SSTR) is an optical measurement technique used to measure the thermal conductivity or boundary conductance of thin films and coatings ranging from a few nanometers up to tens of microns. Use of traditional steady state concepts in combination with a laser based pump-probe configuration allows for measurements of the thermal conductivity of [...]

Overview The measurement of warm touch and cool feel, referred to as thermal effusivity, can be used to compare synthetic materials to their authentic counterparts. As manufacturing synthetic and composite materials have become increasingly popular, the need for materials that look and feel like the authentic material has also grown. In this webinar, we compare [...]

Overview The transient line source technique can be used for the thermal conductivity and resistivity of solid materials such as concrete, natural stone, and low thermal conductivity ceramics. Dr. Cederkrantz discusses his measurements on the materials using the TLS-100. For in-situ and lab testing using the Transient Line Source: TLS-100. Speaker Dr. Daniel Cederkrantz is [...]

Overview Engine oil is an important heat transfer fluid in combustion engines. Overtime, engine oil degrades from heat, pressure, and the collection of debris. Thermtest’s principal scientist, Dr. Sofia Mylona, will investigate the thermal conductivity of new vs. used engine oil and explain her findings in this webinar. About the Speaker Dr. Sofia Mylona is [...]

Overview As the bedding industry encompasses measurements of comfort for feeling of coolness or warmth, also known as Thermal Effusivity, for both initial touch and steady-state sleeping. This webinar will cover how these comfort factors can be measured and used in design in the bedding industry. Speaker Jeff Retallick is a Applications Scientist at Thermtest [...]

Overview Nanofluids are popular due to their enhanced thermal properties as coolants when used in heat transfer equipment such as radiators, electronic cooling systems, or heat exchangers. Our in-house expert will briefly compare thermal conductivity methods for testing liquids and the advantages of testing liquids with the THW-L2. Transient Hot-Wire (THW) is the primary method [...]

Overview For the measurement of non-homogenous and layered materials, thermal conductivity results calculated from measured thermal resistance is the preferred method. A comparison of thermal conductivity ASTM / ISO standards and investigative testing will be presented to explain why this is the case. About the Speaker Dale Hume has more than twenty years of thermal [...]

Overview In this webinar featuring Moisture Wicking Fabrics, we discuss our findings on the effects of moisture wicking fabrics and cool feel performance wear using the Thermal Effusivity Meter (TPS-EFF). Our focus is determining if the TPS-EFF can assist in selecting cool feel materials to be used in athletic wear with varying moisture levels. About [...]

Overview Discussing the measurement of the thermal conductivity and resistivity of soil and concrete using the transient line source technique. The transient line source (TLS) is an ideal and standardized method for testing materials in-situ and in the lab. Thermtest's TLS-100 is an easy-to-use and affordable instrument used for testing soil, rocks, concrete, and polymers. [...]

Overview Discussing the benefit of using the Transient Hot-Wire (THW) method for heat transfer fluids such as ethylene glycol and water. Transient Hot-Wire (THW) is the primary method for the measurement of thermal conductivity of fluids, nanofluids and pastes because of the wide range of applications, its high accuracy and repeatability. According to its theory, [...]
