In an environment that experiences drastically changing temperatures it is potentially more energy efficient to use insulative walls that can change their apparent thermal conductivities. This paper suggests a nano-porous material able to change its thermal conductivity by a factor of 3 varying the pressure upon it from 1 to 100 kPa. Thermal conductivity measurements are made in-situ by an airtight guarded heat flow meter....
Multiple studies claiming the usefulness of nanofluids for the enhancement of heat transport have been proven ill-founded. Although they have significantly raised thermal conductivities, there is an inerrant increase in viscosity when adding nanoparticles to a liquid. This paper explores areas of research that analyze nanofluid properties that could potiential indicate future applications. A promising direction is using particles that can change ...
Hydronic Pavement (HP) is a potential alternative method of spreading sand and salt on slippery road surfaces through embedded pipes that circulate brine, oils, or glycol-water. The present study analyzes the thermal properties involved in designing a HP system. The transient plane source method was used to analyze thermal properties of asphalt with various sensor sizes. Results showed that thermal conductivity varied around 6-14% based on the different depths of ...
