The Center for Innovation through Visualization and Simulation (CIVS) hosted a seminar presented by Dr. Shi-Chune Yao, Professor of Mechanical Engineering, of Carnegie Mellon University (CMU), Pittsburgh, PA. The seminar was held in the CIVS Immersive Theater at 2pm on Friday, August 16. The topic was CMU MEMS Development for Thermal Fluids Micro Systems.
Micro Electronics Mechanical Systems (MEMS) is origin from the micro-electronics technology. The MEMS is heavily dependent on the micro-fabrication technology and various know-how of processing. So far, the successful products include the sensors, lab on the chips, atomic force microscope probes, and generally used as the nano-enabler. At the CMU Mechanical Engineering Dept, over half of the faculty members are involved fully or partially on MEMS and NANO research.
In this presentation, the experience of the MEMS development for thermal fluids micro devices is discussed. This includes the micro channel heat exchangers, micro spray systems, micro fuel cell water management, micro gas bubble separation, and micro refrigeration systems. The current interest of additive manufacturing using micro scale laser sintering of metal powders is also presented.
Dr. Yao of Mechanical Engineering, Carnegie Mellon University (CMU), has been active in fluid mechanics and heat mass transfer research for over 30 years, published over 160 papers. More than 20 Ph.D. students have graduated under his supervision. His research interests covers nuclear power, cooling of electronics, fuel cell development, and spray combustion. In the last 10 years he has focused on MEMS thermal fluids.
Dr. Yao received his Ph.D. degree from the University of California, Berkeley at 1974. After worked at Argonne National Laboratory for three years, he joined Carnegie Mellon University in 1977. In 2005-2006, Prof. Yao served as the interim Department Head at the Mechanical Engineering Department of CMU.
Dr. Yao has been a FELLOW of the American Society of Mechanical Engineers. In ASME Heat Transfer Division, he served as the chairman of Fire and Combustion Committee and the Long Range Planning Committee. He has been serving at the scientific committee in International Conference of Multiphase Flow since 1998, the Program Chair of the Year 2000 National Heat Transfer Conference, and also the Conference Co-chairman, International Symposium on Multiphase Flow and Heat Transfer 2005.
