For HOT DISK TPS2500S what heating power and measurement time are for Low-viscosity liquids (nanofluids)?

14 October 2016 1 4K Report

I have HOT DISK 2500S and need to measure thermal conductivity and specific heat capacity of nanofluids which their viscosity near to water ones.i have tried to measure them but the results were not reasonable!! I wonder what are HEAT POWER and TIME to perform that test ??

Sarah Ackermann

Generally speaking for low-viscosity fluids you want to keep the test time very short and the test power relatively low - else you may introduce convection. I do most of my liquid testing with MTPS as opposed to TPS - but principles are similar. For liquids, MTPS keeps the test time
