Thermal Rectification Effect caused by Ballistic Phonon
Propagation through Asymmetric Nano-Structures

John P. Miller
Department of Mechanical Engineering
Advisor: Professor Christopher Dames

Thursday, June 04, 2009, 10:00 a.m.- 12:00 p.m. WCH Room 203

Abstract: Thermal rectification is a phenomenon where heat is transported though a device more easily in one direction than in the opposite direction. This project begins with the belief that including asymmetric nanostructures in a matrix material will allow energy carriers (in this case, phonons) to travel more easily in one direction than in the reverse. Previous theoretical derivations showed that the heat transfer in such
devices is dependent on the forward and reverse phonon transmission functions, which are determined by the device geometry. In this thesis work, a computer model was developed to calculate the transmission functions using a ray tracing method. This numerical model was validated successfully against known analytical solutions for the size-dependent thermal conductivity of nanowires, thin films, superlattices, and bulk materials, as well the transitions between these different regimes. Finally, the model was used to calculate the thermal rectification in materials containing arrays of pyramidal inclusions. The effects of pyramid surface roughness, aspect ratio, number of layers, and material were studied. The modeling concludes that the maximum thermal rectification effect is obtained by using a single layer of pyramids with smooth sides, a high aspect ratio, and made of a material with a phonon velocity much higher than the matrix material.

May 4

penilla_perezMechanical Engineering Graduate Students, Francisco Perez-Gutierrez (left) and Elias Penilla (right) received the "Chancellor's Dissertation Fellowship Award" and the "Graduate Research Mentorship Program", respectively. These fellowships provide stipend support plus payment of fees for two quarters to each of them. All students who received these awards campus wide (77) were ranked both by their own programs and by a subcommittee of the Graduate Council based on a number of factors including diversity (where applicable), progress toward degree, quality of proposal, and of course departmental/program ranking.

Francisco's proposal is entitled "Interaction of short and ultrashort laser pulses with artificial tissue models and cells", while Elias' is entitled "Materials processing and synthesis of bulk polycrystalline materials". These topics are in line with each of their Ph.D. dissertation plans.

 

On behalf of the ME faculty and staff, congratulations to Francisco and Elias for this great achievement!

Garay's DoD award will enhance research equipment

April 7

machine and Garay Mechanical Engineering Assistant Professor Javier Garay has received an award from the Department of Defense (DoD) to support the purchase of research equipment that will significantly extend the range of materials that can be processed by Spark Plasma Sintering (SPS) and create a one-of-a-kind processing tool.

Sintering is a method for making objects from powder, heating material until its particles adhere to one another. In Spark Plasma Sintering, the heat is generated internally, as opposed to conventional hot pressing where heat is provided by external sources. The SPS process is usually very fast, with the potential of densifying nanosize or nanostructured powders while avoiding the coarsening that happens with traditional methods.

Garay's existing SPS system was designed and built at UCR and has been used successfully in another DoD funded project. This previous experience has enabled Garay to assess critical challenges in the field and identify gaps in apparatus capabilities. He will augment the system with a gas process control and glove box features. These will allow for the suppression of volatility and the processing of materials in an inert atmosphere.

Each year the Department of Defense awards funds for the purchase of university research equipment through a program called Defense University Research Instrumentation Program (DURIP). This program makes possible the purchase of state-of-the-art equipment that augments current capabilities or develops new capabilities for research. The awards are the result of a merit competition conducted by the Army Research Office, the Office of Naval Research and the Air Force Office of Scientific Research.

Dr. Mark Durbin (PI) from CE-CERT and Prof. Heejung Jung (co-PI) of Mechanical Engineering awarded by South Coast Air Quality Management District

January 14, 2009

The impact of emissions from gasoline fueled vehicles is one of the most important for ambient air quality. Over the past several years, the gasoline fuel specifications have undergone several changes. Initially, MTBE was added to the gasoline in California. As water-related issues precluded the use of MTBE in gasoline, ethanol was transitioned in to meet oxygenate requirements. With the push to use increasingly higher levels of renewable fuels, there is consideration to further increase the ethanol level in the fuel. With each transition in the composition of the fuel, it is important to fully understand the impacts the new fuels have on exhaust emissions. The goal of this program is to examine the effects that fuel changes have had or could have on exhaust emissions from modern light-duty gasoline vehicles.
