A study of the potential use of renewable resources to produce polyols, which in turn are used to produce polyurethane. The thermal conductivity of a number of results was taken using the TLS-100 device. This device functions using the transient line source method. A future increase in the production of polyurethane through renewable resources is imperative to reduce the consumption of fossil ...
Energy efficiency in old building is very dependent upon how much heat is escaping through the walls. To determine this it is imperative to know the thermal conductivity of certain solid stone walls. This paper focuses on investigating the properties of some types of common stones used in traditional masonry of Scotland. The TLS-100 device is used to calculate the thermal conductivity ...
A detailed development of a local heat transfer probe specifically designed for analyzing nanofluids. In this paper iron oxide is used as a test subject to determine the accuracy of the probe. Different concentrations were measured ranging between 0 and 0.09% by volume. Thermal conductivity is also measured by a TLS-100 instrument, based on the transient line source. It is shown that the heat ...
This paper explains an addition to a larger NPL project with the purpose to validate the use of the transient contact-probes for measurement of the thermal conductivity of soft solids such as foods, powders, and biological materials. Transient line source methods are used in this paper to accurately measure the thermal conductivities of a large variety of materials. More attention is paid ...
In an attempt to understand the numerous physical aspects of mines, a numerical modeling simulation on the development and dewatering of mines has been presented. The transient line source was used to complete this task. The log approximation was used to find the change in flow rate per unit length of the tunnel....
