Elaine Oran. Elaine Surick Oran (born April 16, 1946) is an American physical scientist and is considered a world authority on numerical methods for large-scale simulation of physical systems. She has pioneered computational technology to solve complex reactive flow problems, unifying concepts from science, mathematics, engineering, and computer science in a new methodology. An incredibly diverse range of phenomena can be modeled and better understood using her techniques for numerical simulation of fluid flows, ranging from the tightly grouped movements of fish in Earth's oceans to the explosions of far-flung supernovae in space. Her work has contributed significantly to the advancement of the engineering profession.

Education 
Elaine Surick is the daughter of Herman E. Surick and the stepdaughter of Doris Luterman-Surick. She is married to Daniel Oran.

Elaine Surick attended school in Philadelphia, Pennsylvania. Bryn Mawr College awarded her a bachelor's degree in both physics and chemistry (1966). She then attended Yale University, where she received a master's degree from the department of physics (1968) and a Ph.D. from the department of engineering and applied sciences (1972).

U.S. Naval Research Lab 
Elaine Oran joined the Plasma Physics Division at United States Naval Research Laboratory (NRL) in 1972. In 1978, she joined the Laboratory for Computational Physics. She worked to start the Center for Reactive Flow and Dynamical Systems, and became its head. In 1988, she became the senior scientist for reactive flow physics.

She has done significant theoretical and computational research on complex dynamic systems' fluid and molecular properties. Her team has created many numerical algorithms and computerized models for accurate numerical simulation of reactive flows. Because reactive flows occur in a broad range of important phenomena, Oran's work has enabled other investigators to examine and describe many previously unexplained reactive flow dynamics.

Reactive flows can involve gases, liquids, solids, or combinations thereof. As these move through space and over time, they may change chemically. Reactive flow problems often involve multiple processes interacting simultaneously. Identifying the boundary conditions where states of matter react and how they interact is important in modeling reactive flows. Physical processes involved in reactive flows include species reactions, diffusive transport, radiative transport, convection, and wave-like properties, some or all of which may be modeled to address a particular problem. Modelling of complex reactive flows has applications in a wide variety of areas including aerodynamics, hydrodynamics, microfluidics, chemical kinetics, chemical process modeling (involving advective and diffusive transport processes as well as chemical kinetics) and combustion-related flame and detonation phenomena.

Reactive flow modeling can be applied to solar and stellar astrophysics to study novae, star formation, and cosmology. It can model mixing in Earth's atmosphere, rarefied gas flow during atmospheric reentry, torpedo launches in the Earth's oceans, the spread of fires in cities and forests, and the behavior of car engines and chemical lasers.

Oran has applied simulation methods to various issues at the Naval Research Lab. She has helped to design biosensors, propulsion systems for rockets and jets, and space and planetary exploration vehicles. She has studied the fundamental physics of combustion processes, applying flow models to flames, detonations, and the conditions underlying the transition to denotation. Her work has supported the safe storage of hydrogen fuels and other energetic materials.

Aerospace engineering 
She is currently a professor at Texas A&M University. She worked at the department of aerospace engineering at the University of Maryland as a Glenn L. Martin Institute Professor of Engineering from 2013 to 2019. She continues to serve as an emeritus scientist at the U.S. Naval Research Laboratory and is an adjunct professor at the University of Michigan and a visiting professor at Leeds University. She is also a senior visiting professor in the Institute for Advanced Study at Hong Kong University of Science and Technology and a distinguished visiting professor at Tsinghua University.

Publications 

She has published extensively in journals and has written a textbook, Numerical Simulation of Reactive Flow (1987, 2005), which is reported to be the most frequently used textbook on the topic.
