The ellipsoid enigma began in 1876 and 1892, when
scientists described how an ellipsoid moved through
surrounding fluid while traveling side-to-side and
rotating, respectively, causing pressure and stress on
the object's skin referred to as surface traction. Brenner
later unified the mathematics for both the side-to-side
motion and rotation.
The new research demonstrated how an ellipsoid's
interaction with fluid can be described using the
same type of simple mathematical pattern that
applies to spheres.
"The pattern has been known for 140 years, and the
fundamental underlying reason for why this simple
pattern has to be true is now apparent because of this
new work being published," Kim said.
John Anderson, President Emeritus of the Illinois
Institute of Technology and a Distinguished Professor
of Chemical Engineering, said, "Dr. Kim's paper
definitively finalizes the 140-year development
of intriguing relationships among hydrodynamic
properties of ellipsoids, relationships that have proven
invaluable to theorists trying to model the motion
of particles in flowing liquids and electric fields. A
fascinating backstory is that Professor Kim maintained
his interest in proving the exactness of these useful
relationships even during his years in executive
management in the pharmaceutical industry and the
National Science Foundation. The crucial spark was
reignited last fall when he was invited to speak in
memory of his late colleague, Howard Brenner."
Anderson visited Purdue to give a guest seminar on
September 22, 2015.
Professor Henry Power of the University of Nottingham,
an expert who provided an important discovery in the
field in 1987, said: "Professor Kim's elegant solution
also provides a new and efficient way for solving for
the motion of these nonspherical particles."
Dr. Sangtae Kim speaks with a graduate student following a reception in his honor.
Professor Kim is the 2013 recipient of a Ho-Am Prize,
a prestigious award presented each year to Korean
individuals who have contributed to academics,
the arts, and social development, or who have
furthered the welfare of humanity.
