Two ME professors win NSF early career awards

Two mechanical engineering professors have been awarded prestigious grants from the National Science Foundation. Tim Shedd and Xiaochun Li were named 2002 recipients of the National Science Foundation's Faculty Early Career Development Award (CAREER), worth $375,000. The awards are granted on the basis of a creative career-development plan that integrates research and education effectively.

Shedd leads the Multiphase Flow Visualization and Analysis Laboratory. He studies fundamental behaviors of multiphase flow, with specific attention to fluid systems common in refrigeration and air conditioning applications.

Shedd and his team plan to develop unique and innovative experimental techniques for quantifying complex interactions between flowing vapors, liquids and solids. For example, they hope to visualize and measure liquid film development throughout a condensation process and study the inception of waves that are critical to heat transfer. He plans to expand these applications to novel two-phase electronics cooling projects in collaboration with faculty in the mechanical engineering department as well as partners in the high-end computing industry. He sees promising opportunities for further collaborative research on multiphase flows in the nuclear and conventional power generation industries as well.

Shedd plans to enhance both graduate and undergraduate education in the thermal sciences through the use of live demonstrations of various kinds of fluid flow, both in the lab and in-class, real-world, project-based collaborative learning techniques, and the involvement of several undergraduate research assistants.

Li's research involves seeking ways to integrate two fields — layered manufacturing and smart materials and structures. According to Li, little work has been done in integrating the two fields at the mesoscale (from 100 microns to 10 millimeters).

"This is an emerging field," he said. According to Li, the mesoscale layered manufacturing technologies have significant implications for the design and fabrication of mesoscale complex structures, filling the voids of 2D microscale processes (silicon surface micro-machining and LIGA process) and 3D macroscale miniature machining.

In addition, Li plans to conduct research on fundamental issues related to mesoscale layered manufacturing processes. He plans to integrate laser-assisted Shape Deposition Manufacturing (SDM) and Laser Direct Write to build mesoscale smart structures containing embedded micro sensors and actuators. Li's goal is to provide insights into how industry can rapidly manufacture smart devices that perform faster and with better precision.

The educational plan of this NSF award is to improve the existing curriculum in the arena of manufacturing by developing new interdisciplinary elements that integrate the fields of layered manufacturing (Rapid Prototyping), micro-/nano- manufacturing and smart materials and structures.
