A Workshop was held on the subject of Thin Film Thermal Conductivity Measurement as part of the Thirteenth Symposium on Thermophysical Properties at the University of Colorado in Boulder CO, June 25-26, 1997. The purpose of this Workshop was to provide a forum for producers and users of thermal properties data to discuss the unique problems associated with measuring the thermal conductivities o...

After giving the theoretical summary of the structure function method for the evaluation the thermal transient measurement results, the broad applicability of the method is demonstrated by practical examples. The first example shows how to control the quality of the die attachment or soldering of packages with fast transient measurements and subsequent evaluation. The second example presents ho...

he increasing amount of heat generated by electronic devices is making devices thermal design and ways to combat heat more and more important issues to deal with. Therefore, we have developed a system able to evaluate thermally conductive materials such as conductive adhesives. The measurement technology is based on the steady-state method, and can evaluate heat transfer characteristics of moun...

in recent decade, the new advanced nanofluids, composed from various particles, have attracted the attention of researchers. this class of nanofluids, which can be prepared by suspending several types (two or more than two) of nanoparticles in base fluid, is termed as hybrid nanofluids. in this work, an experimental investigation on the effects of temperature and concentration of nanoparticles ...

We present an improved methodology for a thermal transient method enabling simultaneous measurement of thermal conductivity and specific heat of nanoscale structures with one-dimensional heat flow. The temporal response of a sample to finite duration heat pulse inputs for both short (1 ns) and long (5 ls) pulses is analyzed and exploited to deduce the thermal properties. Excellent agreement has...

Knowledge about the thermal conductivity is expedient whenever heat transport is involved in a process. As pressure plays an important role in a multitude of treatments or reactions, conductivity measurements have also been carried out under pressure for various substances (e. g. lubricants, plant oils and several foods). Experimental data are needed as this property cannot be derived from equa...

this paper was aimed to address the modeling of effective thermal conductivity and viscosity of carbon structured nanofluids. response surface methodology, d_optimal design (dod) was employed to assess the main and interactive effects of temperature (t) and weight percentage (wt %) to model effective thermal conductivity and viscosity of multi wall and single wall carbon nanotube, cvd and rgo g...

The feasibility of measuring terrestrial heat flow in lakes has been investigated in Lake Superior. The temperature gradient and thermal conductivity of the sediment were measured at each of four stations in water depths exceeding 250 meters. Consideration of the effects of climatic variations suggests that they may not seriously affect the values for heat flow obtained by this method. The valu...
