Abstract or Summary
  • A non-intrusive measurement technique for direct quantitative thermal visualization of channel wall temperatures in two phase microchannel flows using infrared thermography (IRT) is presented. Specifically, the measurement of top channel wall temperatures in a fractal-like branching microchannel silicon heat sink during flow boiling is demonstrated and thoroughly documented. Obtaining quantitative local temperature measurements involving IRT poses significant challenges and requires careful consideration with regard to heat sink design, fabrication and calibration as well as data acquisition, reduction and analysis procedures -- all of which are addressed and discussed in detail. Also discussed and rigorously quantified are the potentially significant measurement uncertainties associated with obtaining non-intrusive, local data of this nature. Results indicate that temperature maps of the microchannel top wall during flow boiling can be obtained with a spatial resolution of 10 μm and an uncertainty varying from 0.82°C-1.67°C at 25 °C and 0.96°C-2.80°C.
