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 ...
Borehole heat exchangers are used in conjunction with ground source heat pumps in Nordic countries. Aqueous ethanol solutions are commonly used with other secondary fluids such as water in borehole heat exchangers to decrease the freezing point of the liquid. However, ethanol based mediums contain denaturing agents that can affect the thermal properties of the secondary fluids. In this study, a Thermal Constants Analyzer used the Transient Plane Source method ...
This study aimed to determine how reliable the Transient Plane Source (TPS) method is when testing semi-transparent materials that have varying extinction coefficients at different temperatures. A numerical experiment has been designed that copies the experimental process and tests the accuracy of the thermal conductivity values that the TPS method generates for semi-transparent materials. After using the TPS Method and comparing the results with the numerical experiment, the study concluded ...
