Through professional societies, Dr. Chehroudi delivers invited professional seminars on Management of R&D Teams and Organizations, Management of Innovation, Combustion and Emission of Pollutants in Automotive and Gas Turbine Engines, Ignition Issues, Gasoline Direct Injection engines, R&D on Homogeneously-Charged Compression Ignition (HCCI) engines, and Liquid Injection Technologies.
Dr. Chehroudi has been involved in, and managed, a number of multimillion-dollar R&D programs with successful results that are being currently used, either as design tools for product development, or have already been incorporated in existing products. Some non-limiting samples are cited here. His rapidly-scanning laser Doppler velocimeter design was the fastest scanner at the time, which was used to characterize separated turbulent boundary layers (turbulence, auto- and cross- correlations. Journal of Fluid Mechanics) similar to what occurs on airplane wings and gas turbine compressors. Space-time correlation coefficients in the backflow region of a separated flow are reported and analyzed for the first time in the literature. Ten (10) years after, this work has passed the test of time and was selected as an outstanding contribution in the SPIE Milestone Series in Laser Diagnostics, edited by Ronald J. Adrian and Brian J. Thompson. Learn more on the stringent selection process used here. One of his works at Princeton University Engine and Sprays Research Laboratory, working with the late Professor F. V. Bracco (also see Aerospace Research & Education at Princeton), sponsored by the Department of Energy (DOE) Direct Injection Stratified Charge (DISC) engine program, a consortium by GM Research Lab, SANDIA Combustion Research Facility, Los Alamos National Lab, and Princeton University, was related to characterization of the dense intact core region in diesel fuel sprays. His multidisciplinary team management and innovative electrical conductivity method produced results that have also time-tested and considered highly-creative and instrumental for the modeling/simulation as well as design of fuel injectors in such engines. Results have been used in the development and validation of the fuel atomization section of the KIVA computer program, being the backbone of most combustion modeling simulation in internal combustion engines. For this work he and his team members were awarded one of the most prestigious technical merit award (Arch T. Colwell Merit Award) by the Society of Automotive Engineers (SAE). Also, another work conducted on aircraft and ground-based gas turbine engine fuel spray combustion and emission issues was cited in the CRC Handbook of Fluid Dynamics as "significant example of applied engineering research done on the subject with many commercial applications". His interacting-sprays (or impinging-sprays) injection strategy (Sponsored by the General Motors) for simultaneous NOx and soot reduction/control, a cross fertilization of rocket F-1 engine technology to diesel engines, is considered an ingenious approach with highly flexible features to produce not only "pilot and split injections," but additional strategies for emission reduction and efficiency improvements. A chapter is dedicated to "Interacting Sprays" injection by Prof. J. B. Greenberg in the Handbook of Atomization and Sprays. This concept has recently been used in diesel engines modified for the early-injection homogeneously-charged compression ignition (HCCI). His original work established a new research track on application of interacting sprays or impinging sprays in diesel engines (see Chehroudi's presentation on Interacting Sprays). Watch a video describing details of the Interacting Sprays Injection System Test Setup (High-speed internet recommended). Yet another example, is his leadership on a program related to supercritical cryogenic liquid propellants used in H2/O2 Space Shuttle Main Engine (SSME). This work, and his team, were recognized by another highly prestigious technical merit award through Combustion and Fuel Technical Committee of the American Institute of Aeronautics and Astronautics (AIAA). His Invited Review article on this subject is titled "Recent Experimental Efforts on High-Pressure Supercritical Injection for Liquid Rockets and Their Implications. Dr. Chehroudi's newly-proposed combustion instability theory for liquid rocket engines is yet another unique contributions recognized by his peers as innovative and highly creative. Expansion of his work into nanotechnology also produced the only nanotechnology-based light-activated volumetrically-distributed ignition system for both automotive (HCCI) and rocket engine applications. His creative idea and the R&D work he directed, delivered an elegant answer to a technological barrier referred to as "controlled autoignition", being at the heart of the next generation advanced HCCI engines. His innovative imagination, initiative, leadership, and technical vision in this area have, not only set the stage and the R&D roadmap for new applications of nanotechnology in volumetrically-distributed fuel/propellant ignition for the first time in literature with subsequent followers, but also convinced program managers at AFOSR in creating a fully-funded five year program for this work while at AFRL.
Throughout years, Dr. Chehroudi has evolved into a leader who forms synergy, cultivates a culture of innovation and collaboration, communicates unambiguously and respectfully, builds trust and consensus, injects motivation and inspiration, and guides/encourages strategic/systemic thinking. These incipient talents are those he has nurtured through interactions with colleagues/mentors which have been critical and precious elements facilitating stellar achievements from his teams. Moreover, he brings extensive level of technical leadership and presentation skills (to technical/nontechnical, C-level, & clients) in a broad range of disciplines/technologies, which are instrumental in leading multidisciplinary teams, in technology development, forecasting and transfer, as well as in revenue-generating new product development (NPD) and R&D efforts. Lastly, when a solid educational background (PhD/MS/BS in Mechanical/Aerospace Engineering and MS in Economics/Management) is added to the mix, the package as a whole creates a multidimensional professional who understands and quickly grasps the importance and potential of research/development activities for commercialization in a wide range of science, technology, and engineering fields and who markets such opportunities and ideas towards goals/objectives of the organization.
Dr. Chehroudi has a PhD in Mechanical & Aerospace Engineering and Post-Doctoral Fellow (Princeton University), MS in Mechanical Engineering (Southern Methodist University, Summa Cum Laude), MS in Economics (Swiss Finance Institute, Magna Cum Laude), and BS in Mechanical Engineering (Sharif University of Technology). He is a senior member of the American Institute of Aeronautics and Astronautics' Propellant & Combustion Committee (2008-present) and was honored an Associate Fellow title from the American Institute of Aeronautics and Astronautics.
He acts as a reviewer for many scientific and engineering journals and publishers, has been the Technical Editorial Director of the Powertrain Magazine for over ten years, and is a member of the Editorial Board of the Journal of Combustion by Hindawi. Dr. Chehroudi has delivered over 200 presentations in technical meetings/conferences (SAE, AIAA, ASME, ILASS, Professional Education Seminars, etc) and to nontechnical audiences and has over 20 technical reports (Princeton University, General Motors, Ford Motor Co, Department of Energy, NASA, Air Force Research Laboratory).
He has also produced five 600-plus-page monographs on combustion and emission of pollutants from mobile power plants, ignition technologies, liquid fuel/material injection, and nanotechnology, two book chapters on liquid propellants and combustion instability and applications of graphene (a nanotech product) in ignition and combustion of fuels/propellants, ground-breaking patents on applications and synergy between nanotechnology, light, and chemical reaction for a light-activated volumetrically-distributed ignition of fuel-air mixtures and liquid fuel sprays with applications in Low Temperature Gasoline Combustion (LTGC) or HCCI, and liquid rocket engines.
Dr. Chehroudi has more than 150 publications with extensive experience in both scientific and management areas and intensive trainings in finance and financial engineering.
