Overview Vehicles require constant care and attention to function properly. Fluid maintenance is a key preventive measure that extends the longevity of your vehicle and is one of the most critical elements of your vehicle's functioning. In our latest webinar, we test several different fluids for the various sub-systems within a vehicle with the Transient [...]

Overview In applications such as heat transfer, thermal management, etc. nanofluids and nanolubricants aid in reducing friction while also improving functionality and efficiency. Dr. Sofia Mylona an internationally recognized expert in the area of thermal conductivity measurements using the Transient Hot-Wire method dives deeper into the subject of measuring the thermal conductivity of nanofluids and [...]

Overview When measuring homogeneous or heterogeneous materials, it is important to consider steady-state vs. transient testing methods and how this will influence the measurement of thermal conductivity. This webinar looks to further the conversation on this topic to explain why steady-state is the preferred method for heterogeneous materials: whereas transient methods result in a bias. [...]

Overview In this webinar, Dale Hume dives into testing materials at high temperatures with Thermtest’s new Guarded Heat Flow Meter-01. The advanced GHFM-01 is a primary measurement of thermal resistance—thermal conductivity for solids, such as metals, polymers, composites, and paste. Specifically, the calculation of thermal conductivity from the measurement of thermal resistance is the most [...]

Overview Cryogenic testing explores the behavior of materials at extremely low temperatures. When chemicals are exposed to ultra-cold temperatures the properties of those chemicals change. This provides an intriguing area of study for researchers. These studies have led to advances in gaining a better understanding of materials while also creating entirely new technologies and industries. [...]

Overview The relationship between water and soil thermal conductivity or resistivity is referred to as a thermal dry-out curve. The thermal conductivity of soil is directly related to the amount of moisture contained within the soil and depends strongly on the water content, composition within the soil, temperature, and bulk density. Dry-out curves are used [...]

Overview In this webinar, Thermtest’s Product Line Manager for the Transient Hot-Wire (THW) method will discuss the Thermal Conductivity of liquids using our in-house THW L-3 sensor. The THW-L3 sensor is fully compatible with Thermtests MP-2 portable device. The sensor uses the Transient Hot-Wire method to measure the thermal properties of liquids and pastes. With [...]

Overview Proper thermal management in electronics is crucial for reliability, speed, and efficiency. With thermal conductivity playing an important role in making electronics perform properly, we will explore ways to measure thermal conductivity using Steady-State Thermoreflectance fiber optics (SSTR-F). Silicone, non-silicone gap pads, gap filling materials and potting of resins are common techniques for thermal [...]

Overview One of the disadvantages in modern buildings are the lack of thermal mass, meaning that buildings cannot contain heat in the winter and overheat in the summer. More times than not, cooling and heating systems are installed in buildings to maintain a comfortable temperature. However, with the use of phase change materials (PCM) it [...]

Overview In this webinar, we compare three different methods for testing the measurement of thermal conductivity. The methods explored will be the Guarded Heat Flow, Transient Plane Source, and Laserflash and furthermore using these methods for testing of graphite samples. This will then lead us into the discussion of the effects of thermal shunting on [...]

Overview Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization is the process of heating liquid food above 135 °C (275 °F) for 2 to 5 seconds to kill bacterial endospores and sterilize the liquid. Originally used to prolong the shelf life of milk, Ultra-high temperature processing is now used in a wide range of liquid [...]

Overview For the measurement of rigid and compressible insulation material, thermal conductivity results calculated from measured thermal resistance is the preferred method. A comparison of thermal conductivity ASMT/ISO standard and investigative testing will be presented to explain why this is the case. This is a part two of our steady state webinars. About the Speaker [...]

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 [...]
