Through the use of thermal conductivity and moisture related measurements, this article investigates the physical properties of undergarments of different compositions (cotton, polyester, rayon, viscose, etc.). This research is used to determine which types of materials would best be suited for use in sports/day-to-day/comfortable clothes. Important properties measured include the porosity of the material as that affects the ability for moisture to be released, as well as the ...
Outlines the problems with measuring the thermal conductivity of low-density insulating materials and addresses this by proposing a three layer method for the accurate measurement of thermal conductivity. This method involves a sample being placed between two conducting brass plates (one heated via hot plate) and monitoring the temperatures of these two plates as the experiment progresses. Mathematical equations are derived in order to make an accurate model for thermal ...
This paper studied in-depth the transient hot plate method, by comparing this method to others in order to develop a short test time in which thermal effusivity and thermal conductivity can be measured simultaneously. To investigate this proposed model, four metal samples were analyzed using various techniques to ensure the accuracy between methods. To encompass a wide thermal conductive range, the thermal conductivities of the four metal samples tested, ranged ...
