H2O/KCOOH (potassium formate) is a highly soluble hygroscopic salt solution that has the potential to be used as a desiccant. However, the thermophysical properties of H2O/KCOOH are only available for concentrations between 20-50%, which is not beneficial for their use as dehumidifiers. In this paper, a TPS system was used to measure the thermal conductivity of H2O/KCOOH solution with salt concentrations of 60-80% between 1 °...
This article reviewed the methods that are available to test thermal properties of various insulating materials. These methods can fall under one of two categories: steady state techniques and non-steady (transient) techniques. The transient plane source (TPS) method is classified as a non-steady state technique. The TPS sensor is a round piece of engraved nickel that conducts electrical currents and is covered with a coating of Kapton, Mica or Teflon. ...
Titanium is used in surgical tools and bone implants because it is strong, has a low density, is resistant against corrosion, and most importantly has a high biocompatibility which reduces the risk of implant rejection. The Transient Plane Source (TPS) method was used to generate a temperature difference curve comparing 2 x 2 inch electrospun coated sheets of Titanium to bone. Results showed that Titanium had a higher thermal conductivity than bone, ...
Fiberglass is used inside car mufflers as a noise reducer and insulator. The insulating properties of the fiberglass eliminates the need for muffler heat shields, however to properly design vehicles without heat shields, it is important to know the thermal conductivity of fiberglass at high temperatures. A TPS Thermal Constants Analyzer was used to measure the thermal conductivity of glass fibers with diameters of 17 µm and 24 µm. Each sample was ...
Phase change materials (PCMs) are materials that store thermal energy and undergo phase transitions when they are heated and cooled, making them effective alternatives to fossil fuels for building insulation. To determine the energy performance of PCMs in infrastructure it is important to understand their thermal characteristics. The transient plane heat source (TPS) method was used to determine the thermal conductivity of the PCMs ClemSel 21 and ClemSel 24. The thermal conductivities ...
