Recently, the College of Engineering alumnus Xiang Yang was selected the 2017 Andreas Acrivos Dissertation Award in Fluid Dynamics Recipient by the American Physical Society (APS). He was selected "for developing the novel integral wall modeling concept for large eddy simulations based on fundamental principles and for groundbreaking insights into the scaling implications of the attached eddy model for understanding fluctuations in wall-bounded turbulent flows."
Alumnus Xiang Yang
As the second largest physics organization in the world, APS selected one recipient each year to provide recognition to exceptional young scientists who have performed original doctoral thesis work of outstanding scientific quality and achievement in the area of fluid dynamics.
Xiang Yang received his B.S. in mechanical engineering from College of Engineering, Peking University in 2012, supervised by Prof. Shiyi Chen and Yipeng Shi. He received his Ph.D. in mechanical engineering in 2016 from Johns Hopkins University, where he was advised by Professor Charles Meneveau and Professor Rajat Mittal. Dr. Yang’s doctoral thesis was on modeling of drag forces and velocity fluctuation statistics in wall-bounded flows at high Reynolds numbers.

Yang is now a postdoctoral researcher at the Center for Turbulence Research at Stanford University, working mostly with Professor Parvin Moin. His current work focuses on near-wall turbulence modeling, where he attempts to use the multi-fractal formalism, which was developed for the energy cascade process, to model processes in wall-bounded flows. He also studies wall-modeled large eddy simulation, where he uses this cost-efficient computational tool for problems with strong heat transfer and fluids with variable properties. Dr. Yang has been a member of the American Physical Society since 2013.
Benjamin Levich, Director
1979 - 1987
After a six-year struggle and with help from the international scientific community, as well as a visit to the Soviet Union by Senator Edward M. Kennedy, Professor Levich and his wife were finally allowed to emigrate from the Soviet Union to Israel in 1978. [Please click here to view May 20, 1980 letter from Senator Ted Kennedy concerning Benjamin Levich]. Upon his arrival in Israel, Professor Levich received offers of employment from several universities in the United Kingdom, the U.S. as well as many other countries. However, in March, 1979, he finally accepted the invitation to become the Albert Einstein Professor of Science at City College, where he established the Institute of Applied Chemical Physics and became its first director. Professor Levich was internationally acknowledged as a reknowned physicist, who authored an influential text, Physicochemical Hydrodynamics, which was published by Prentice-Hall in 1962 (translated from the Russian version first published in the Soviet Union in 1952). Physico-chemical hydrodynamics, which is a term Professor Levich coined himself, refers to phenomena governed by the interaction of fluid mechanics, heat and mass transfer, and chemical reactions. The broad aim of the Institute was to investigate key problems in this area from a fundamental and multifaceted perspective. The official charter for the Institute was approved by the City University of New York Board of Trustees on August 6, 1979. It was after Professor Levich's untimely death in January, 1987, that the Institute was renamed, in his honor, as the Benjamin Levich Institute for Physico-Chemical Hydrodynamics.
