Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
One way to increase the thermal conductivity of a conventional fluid is to add solid particles to the liquid. Aluminum nitride (AlN) is an effective thermal conductor so it is popularly used to fabricate nanofluids. In this study, 20 nanometer particles of AlN were distributed into ethanol and the thermal conductivity of the solution was measured using a thermal constant analyzer from 0.5 volume fraction (vol%) to 4.0 vol% at 273.15 kelvin (K) and 297.15 ...
Using magnetic striation and ultrasonic agitation, aluminum nitride particles were dispersed into ethanol. The method was used to measure the thermal conductivities of these aluminum nitride-ethanol nanofluids. Results show about 20 % increase in the thermal conductivity of ethanol and a strong temperature dependence of the thermal conductivity....
