Professor (Joint Appointment)

Chemical Engineering and Materials Science

Dr. Rangel is interested in heat transfer, fluid mechanics, spray combustion, two-phase flows, fluid instability and atomization.

Dr. Rangel's current research activities focus on metal solidification in materials processing, droplet spray vaporization and combustion, and fluid mechanics and heat transfer of small particles in suspension.

The overall goals of the first project are to develop models for droplet deposition on flat and uneven surfaces, and to investigate the stability of solid fronts. In the second project, Dr. Rangel is looking at droplet streams and interaction effects, radiation absorption, ignition of droplet clouds and vaporization of binary droplets. The third effort is aimed at analyzing particle motion in unsteady Stokes flows.

Dr. Rangel also is studying the dynamics of aerosols, liquid atomization, and filling liquid acquisition devices in microgravity environments

Dr. Dunn-Rankin studies combustion, sprays and particles using optical diagnostics and laser spectroscopy.

Generally, Dr. Dunn-Rankin is interested in the fundamental information that can be obtained from simplified systems, such as linear droplet arrays, two-dimensional gas burners, and sub-scale ventilation and biomedical environments, which mimic a specific behavior in more complex systems. Using non-intrusive laser diagnostics, he probes the simplified systems in order to develop physical insight into influencing factors.

His current research activities include a study of the electrical aspects of microgravity combustion; an effort to develop techniques to measure the size of airborne droplets and particles using laser light scattering; and development of a hydrogen-enhanced IC engine. Dr. Dunn-Rankin also is studying combustion control, the formation of droplet streams at high ambient density, and acoustic interactions with burning droplets.

His work can be applied in the area of combustion for size reduction, performance improvement, and emissions reduction in the area of spray processing for the novel production of biomedically relevant materials.

The Henry Samueli Endowed Chair in Engineering and Professor

Mechanical and Aerospace Engineering

Office: EG 3202
Lab: EG 3101

Dr. Sirignano is interested in combustion theory and computational methods, fluid dynamics, multiphase flows, and propulsion and power.

His current research activities address the problems of the vaporization and burning of liquid fuels in very small volumes, turbulence-droplet interactions, distortion and breakup of thin liquid streams, flame spread across liquid fuel pools, and a study of combustion in high speed flows. The applications of the research include miniaturization of combustors, spray technologies, fire safety, and a new high-performance technology for combustion in the turbine stages of a gas-turbine engine.

Dr. Sirignano leads the Combustion, Fluid Dynamics and Propulsion Group and is the director of the Spray and Droplet Science and Technology Center at UCI.

Advanced Power and Energy Program

Director

National Fuel Cell Research Center

Dr. Samuelsen is interested in energy conversion, fuel cells, combustion, fuel sprays, laser diagnostics, air quality, turbulent transport, alternative fuels, the modeling of reacting flows, practical energy systems, and the conflict between energy and the environment.

Dr. Samuelsen's current research activity focuses on energy generation, distribution and utilization, and includes the production of electricity, motive power and propulsive power from both fuel cells, gas turbines and hybrids of both. His work also explores the environmental impact of these energy systems, the dynamic between energy generation and atmospheric quality, and the development of environmentally preferred, high-efficiency energy generation integrated into buildings and building complexes.

Dr. Samuelsen directs the Advanced Power and Energy Program (APEP), which encompasses the National Fuel Cell Research Center (NFCRC), the UCI Combustion Lab (UCICL) and the Pacific Consortium on Energy and the Environment (PARCON).

His work at the UCICL is directed toward the development of advanced stationary gas turbine power systems. Research at the NFCRC is leading the evolution of power generation fuel cells, and the PARCON accelerates the development and deployment of advance energy systems around the world.
