A technique for spatially resolved wall temperature measurements in microchannel heat sinks using infrared thermography

Creator:: Krebs, Daniel P.
Abstract:: 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...

Performances and kinetic studies of hydrotreating of bio-oils in microreactor

Creator:: Attanatho, Lalita
Abstract:: Hydrotreating reaction of vegetable oil is an alternative method for the production of renewable biodiesel fuel. This reaction involves conversion of triglycerides into normal alkanes, leads to a deoxygenated and stable product, which is fully compatible with petroleum derived diesel fuel. The hydrotreating process uses hydrogen to remove oxygen from...
