A comparison of nanofluid thermal conductivity measurements by flash

Some researchers argue that the anomalous k enhancement data, for nanofluids, is caused by inaccuracies of thermal measurement methods. In this paper, measurements on thermal conductivities of nanofluid mixtures (alumina/water) by means of two different methods are accomplished. The thermal conductivity was measured, and through the laser flash method, with the NETZSCH LFA 447 NanoFlash. Five samples of nanofluid, with varying alumina concentration was tested (0.1%, 0.5%, 2.0%, 3.0%, and 4.0%). The deviations between the ...

Measurement of thermophysical properties in semi-infinite media by random heating and fractional model identification 

This article briefly explains the transient plane source technique. This method is used to simultaneously measure thermal conductivity and thermal diffusivity of solids. A Kapton insulated nickel sensor emits electrical currents into a sample that is sandwiched around the heat source which measures thermal properties....
