Li Ding, Ph.D., P.E. (VA)
President and Principal Engineer
Dr. Li Ding is a Principal Engineer at Flow Science and is the technical lead for the Computational Fluid Dynamics (CFD) and and Surface Water Quality & Hydrodynamics groups. He has expertise in CFD software to perform detailed flow analyses within water/wastewater storage and treatment facilities, to design baffles, alternative inlet/outlet configurations, and mixing systems for improving water quality. He is also experienced in the use of the Stanford University Large Eddy Simulation (LES) model. Dr. Ding has conducted numerous hydrodynamic and water quality studies of lakes, reservoirs, and estuaries using the one and three-dimensional DYRESM and ELCOM/CAEDYM models. He is the author or co-author of several publications in refereed journals.
Mark Sauter, M.S., P.E. (CA)
Vice President and Principal Engineer
Mr. Sauter heads the Hydraulic and Transient Analysis group. He gained comprehensive experience in the planning, design, construction and startup of wastewater treatment facilities while an employee for the City of Los Angeles and the County Sanitation Districts of Los Angeles County. His wastewater background serves as a specialized foundation for his applied experience in fluid flow analysis. With Flow Science, he has been responsible for the modeling and analysis of hydraulic transients in pipeline systems as a result of loss of power to pump stations, pump startup, and control valve operations and performs surge analyses for both water and wastewater systems.
