Thermal analysis of nanofluids in microfluidics using an infrared camera
journal contribution
posted on 2012-07-21, 00:00 authored by P Yi, A Kayani, A Chrimes, K Ghorbani, Saeid Nahavandi, K Kalantar-zadeh, Khashayar KhoshmaneshWe present the thermal analysis of liquid containing Al2O3 nanoparticles in a microfluidic platform using an infrared camera. The small dimensions of the microchannel along with the low flow rates (less than 120 μl min−1) provide very low Reynolds numbers of less than 17.5, reflecting practical parameters for a microfluidic cooling platform. The heat analysis of nanofluids has never been investigated in such a regime, due to the deficiencies of conventional thermal measurement systems. The infrared camera allows non-contact, three dimensional and high resolution capability for temperature profiling. The system was studied at different w/w concentrations of thermally conductive Al2O3 nanoparticles and the experiments were in excellent agreement with the computational fluid dynamics (CFD) simulations.
