Microscale ThermalFluids Engineering



Microscale thermal–fluids engineering uses thermal and fluid sciences to develop an understanding of microscale phenomena and applies that understanding in developing new and useful technologies. Thermalfluids engineering faculty at Oregon State are conducting research related to microscale flow visualization, experimental investigations of microscale thermal and fluids phenomena, and the development of microscale thermal devices and integration microscale systems. Technologies being developed within this research group include branching fractal heat exchangers and heat sinks, microchannel bubble absorbers, high flux heat exchangers, microscale energy conversion devices, compact heat actuated coolers, and compact kidney dialysis systems.   

Microscale thermalfluids engineering research at Oregon State is supported by a range of sources including DARPA, Department of the Army, Department of Energy, NASA, Office of Naval Research, Oregon Nanoscience and Microtechnology Institute, and industrial partners. OSU thermalfluids faculty have published articles in refereed journals such as Journal of Power and Energy, International Journal of Heat and Mass Transfer, Journal of Heat Transfer, Journal of Fluid Mechanics, Microscale Thermophysical Engineering, Experimental Thermal Fluid Engineering, Microfluidics and Nanofluidics, Heat Transfer Engineering, Measurement Science and Technology, and Physical Review Letters. Microscale thermal fluids faculty are active in the American Society of Mechanical Engineers (ASME), American Institute of Aeronautics and Astronautics (AIAA), American Society of Engineering Education (ASEE), and American Physical Society (APS).
