Justin presented work on the Local modification of phonon properties at solid-solid interfaces and the effect on thermal transport and MacKenzie presented work on Phononic Properties at Interfaces Below, Near, and Above the Debye Temperature. For his exceptional work and presentation MacKenzie was awarded 1st place among young PhD candidates in the schools poster competition in memory of Roger Kelly.

MAE Students Receive Prestigious NDSEG Fellowships

Several students  in the mechanical and aerospace research labs have been awarded the National Defense Science & Engineering Graduate (NDSEG) Fellowship.  Sponsored by the Department of Defense, this prestigious fellowship gives leading students the increased freedom and flexibility to pursue research interests in cutting-edge science and technology.

Nanoscale Energy Transport Laboratory:

  • MacKenzie Sinden-Redding is using Time-Domain Thermoreflectance (TDTR) measurements to experimentally investigate nanoscale thermal transport processes in real material systems. In particular, MacKenzie is studying the thermal transport across interfaces between dissimilar solid materials in an effort to understand the underlying phonon physics. This work is intended to improve the current state-of-the-art of thermal interface materials, thermoelectric devices, micro-electronics, and other nanoscale systems. During this time, MacKenzie is also working with another graduate student (Justin Smoyer) to develop changes to the TDTR facility which will allow for a versatility in data collection that will greatly extend the capabilities of the system.
  • Chris Baker is using molecular dynamics simulation to investigate the fundamentals of phonon scattering in nanoscale material systems.  Christopher plans on using the wavelet transform to extend the capabilities of computer simulation to study the fundamentals of phonon transport in material structures of varying morphology and composition.  Answering fundamental questions on phonon transport will facilitate the design of next generation nanoscale materials with applications ranging from electronics to spacecraft heat shielding.

Aerospace Research Laboratory:

  • Ryan Johnson is using Using High Performance Computing to Model Chemically Reacting Flow Fields.  The focus of this project is on using computers and super clusters to model the physics of multi-dimensional, chemically reacting, fluid dynamics.  The large amount of memory required to track these quantities causes the simulations computationally expensive which is why several computers connected together so that results are produced in a timely manner.  Applications of this research can range from the flames found in hypersonic combustors to the ablation of the space shuttle during re-entry.

Chris Baker presented  “Thermal Rectification for the Enhancement of Heat Transfer” at the ASME 2012 Summer Heat Transfer Conference in Puerto Rico.  

Chris works in the Nanoscale Heat Transfer Lab directed by Associate Dean Pamela Norris.

Abstract of  “Thermal Rectification for the Enhancement of Heat Transfer”:  Presented is an application of thermal rectifiers to the thermal management of ordinary and stacked computer chips. The computer chip is modeled as an array of point heat sources connected by thermally rectifying interfaces. We orient the thermal rectifiers such that heat transport is promoted in the direction of the boundary of the chip. The heat flux from the chip is computed at steady state for a variety of system parameters. Investigated are the effects of the thermal rectification ratio, the device dimensions, and the duty cycle. This approach can be used to spread heat in the lateral dimensions of an ordinary computer chip and greatly increases the heat flux from the stacked configuration.

SEAS MURI Award Paves Way for All-Electronic Navy

Aug. 9, 2007 — Two hundred years ago, as fans of Master and Commander know, the power of a warship was reflected in the size of its guns and the weight of it broadside. Today, one of the most important criteria is the sophistication of its electronics. Modern warships are packed with powerful radar, sonar, communications, navigation, and weapons systems that depend on sophisticated integrated circuits and advanced processors. The U.S. Navy now plans to rely completely on electronic systems in its next generation of destroyers, substituting electricity to power the tasks currently assigned to gas turbines, pressurized air, steam, and other means of propulsion.

U.Va. Mechanical and Aerospace Engineering Women Excel at Home and in the Lab

From left to right: UVa Professors Hillary Bart-Smith, Pamela Norris, and Silvia Blemker.

February 5, 2009 — University of Virginia mechanical and aerospace engineers Pam Norris, Silvia Blemker and Hilary Bart-Smith are rare among their colleagues in the field.

It’s not because Norris is a tenured full professor with six active research projects representing nearly $9 million in funding. Or because Blemker maintains a joint appointment in orthopedic surgery at the U.Va. Medical Center as she explores the clinical applications for computer models of human muscles. And it’s not because Bart-Smith is a Packard Fellow and lead principal investigator for a U.S. Department of Defense Multi- University Research Initiative.

It’s because they are women — women who are successfully pushing the limits of engineering research and teaching while balancing a family life.  [More]
