Hi PSAS, You might find this Physics deptartment lecture interesting next Monday. May inspire payload experiment(s)?

Such systems include liquid fuels and cryogens storage tanks, thermal fluids for temperature control, and water processing equipment for life support. A variety of recent ‘low-g’ experimental demonstrations and discoveries will be presented from experiments performed on the International Space Station, in a new drop tower facility, and in a traditional microfluidics laboratory. Concerning the former, robotic experiments currently on orbit are controlled 24-7 from the Portland State University campus ground station where students of the Mechanical and Materials Engineering Department send tens of thousands of commands to the ISS to complete the science objectives. Results to be highlighted concern capillarity-driven flows in complex geometries, critical geometric wetting, inertial-capillary multiphase flow, and passive phase separations. A quantitative understanding of such phenomena is essential for robust spacecraft systems design and examples of pending advanced applications will be discussed. We are enjoying the work thoroughly. Short Bio: Mark Weislogel (Ph.D. M.E., Northwestern, 1996) has conducted fundamental and applied thermal/fluids research, systems analyses, and engineering research and development since 1986. He has 10 years aerospace experience working with NASA, specializing in microgravity capillary flows and phenomena leading to numerous drop tower tests, low-g aircraft campaigns, and space flight experiments aboard the Space Shuttle, Russian Mir Space Station, and the International Space Station. He has over 4 years experience in industry designing lightweight carbon structures, passive cooling cycles, and large length scale capillary systems. Weislogel is currently a professor at Portland State University since 2001 and his research interests continue to focus on macroscale and microscale capillary-driven flows in complex geometries, passive cooling systems, microscale thermal devices, and microgravity fluid mechanics. Weislogel has over 70 publications and four patents. His teaching emphasis centers on the thermal/fluids sciences. _______________________________________________ psas-team mailing list psas-team@lists.psas.pdx.edu http://lists.psas.pdx.edu/mailman/listinfo/psas-team This list's membership is automatically generated from the memberships of the psas-airframe, psas-avionics, and psas-general mail lists.
