Abstract
A new constant power line heat-source temperature sensor was developed at Harbin Institute of Technology (HIT), China. This sensor was based on the line heat-source method, and it can be applied to determine the thermal conductivities of porous mediums at different depths. The application setup was also introduced in this study.
Highlights
Porous mediums are quite common in our daily life in engineering applications, geology researches, architecture structures, food science astronautics, and so on
The objective of this study was to introduce a new constant power line heat-source temperature sensor which can be used to determine the thermal conductivities of porous mediums at different depths
The constant power line heat-source temperature sensor consists of an inner power cord with a total length of 160 cm, eight temperature sensors with an interval of 20 cm, and an outer copper pipe with a total length of 160 cm
Summary
Porous mediums are quite common in our daily life in engineering applications, geology researches, architecture structures, food science astronautics, and so on. A number of methods are available for determining the thermal conductivities of porous mediums, and these can be classified to steady-state and transient unsteady-state techniques.
