Professor at UC Irvine
Professor Sirignano was a Professor at Princeton University from 1967 to 1979 after receiving his Ph.D. from there in 1964. He was the George Tallman Ladd Professor and Department Head at Carnegie-Mellon University from 1979 to 1984 before becoming the Engineering Dean at UCI. He left the deanship and currently he holds the Henry Samueli Endowed Chair in Engineering at UCI.
Professor Sirignano's major forefront research accomplishments include:
- Analysis predicting periodic nonlinear oscillations with shockwaves in an unstable combustor
- Explanation of the nonlinear fluid dynamics associated with Helmholtz resonators
- Determination of admittance for oscillatory, three-dimensional nozzle flows
- Theory for condensed-phase behavior in flame spread above liquid and solid fuels
- Theory for ignition of combustible gas by a hot projectile
- Resolution of turbulent flame and propagation in reciprocating and rotary internal combustion engines
- Theory of droplet vaporization and convective heating with internal circulation; computational methods for spray flows
- Theory of droplet interactions in a dense spray; and analysis of driving mechanisms for combustion instability in rockets and ramjets
- Concept and analysis for improved efficiency and increased thrust with turbine burners
- Concept and analysis for miniature combustors with liquid-fuel films
Information for Students
There will be positions for new graduate students this next Fall 2013 in our research group. Stipends and support for tuition and fees can be available when required for admitted students. Many prospective students informally send a CV and ask for an evaluation of the likelihood of gaining entrance. Professor Sirignano attempts to respond promptly but without any evaluation to an inquiry by a prospective graduate student. It is not possible to make a meaningful assessment of any individual's qualifications or likelihood of success at admission without seeing the completed formal application with reference letters in the standard format, transcripts, and official reports of GRE scores. So, it is best to make the formal application if you have a strong interest. If you note on your application that you have a special interest in performing your research for the MS Thesis and / or PhD dissertation with Professor Sirignano, that application should be circulated to him by our administrators responsible for application processing and then he will carefully examine it.
As noted elsewhere in this web site, graduate students who have worked with Professor Sirignano have generally enjoyed very successful professional careers in academia, government, and industry. Several topics of major interests are studied within the group at any one time. The list of publications and the copies of slide presentations for research seminars, given elsewhere in this web site, should provide a useful overview of the research activities. The available graduate courses and degree requirements can be found at the UCI MAE web site http://mae.eng.uci.edu
Many undergraduate students from foreign universities communicate with us requesting a research internship with Professor Sirignano. We only accommodate foreign undergraduate students who are prepared to pay their own costs and can stay for a period of at least one year, which is a minimal time to accomplish a significant piece of research. We receive a large number of internship requests; so, if the ability to spend a year is not clearly stated in the communication from the student, we do not respond.
