Characterizing the Thermal Conductivity of PCMs and HTFs at Elevated Temperatures and Pressures
C-Therm offers unique commercial capabilities in characterizing fluids at both elevated temperatures and pressure conditions. Learn more about our specialized solutions for characterizing the thermal conductivity of heat transfer fluids and phase change materials.
Heat Transfer Fluids(HTFs) are applied in a wide range of applications; In the chemical and petrochemical processing industries, heat transfer fluids play a vital role in production. Productivity, safety and environmental issues are paramount concerns in the oil and gas industry. Properly understanding the thermal conductivity of materials at elevated pressures and temperature is critical to sound process safety. In solar operations, there is similar need for high performance heat transfer fluids that offer long life, and precise temperature control. And in asphalt plants – the use of heat transfer fluids in production, heating and storage applications is necessary. HTFs are employed for the purpose of heating thousands of gallons of stored asphalt in terminals, heating aggregate in cold, harsh temperatures, and batch processing. In all applications, the thermal conductivity of the HTF is considered a critical performance attribute of the material - necessitating a reliable, high-accuracy means of testing.
Phase Change Materials (PCMs) are substances that absorb and release thermal energy during the process of melting and freezing. When a PCM freezes, it releases a large amount of energy in the form of latent heat. PCMs can be applied in materials of construction for housing, sportswear/textiles and bedding in providing latent heat thermal energy. They can also be applied in electronics for cooling purposes. One of the challenges to wider commercial success and adoption of PCMs for such application is the relatively low thermal conductivity of traditional PCMs. Efforts are underway to increase the thermal conductivity of traditional PCMs by incorporating additives such as graphite and other higher thermal conductivity materials.
