Gang Zhao, Ph.D., P.E. (CA)
Dr. Zhao is currently a Principal Engineer at Flow Science. His field of specialization is hydrodynamics and water quality modeling. He also has experience in field tracer studies, hydrologic modeling, GIS analysis and NPDES permit applications. Dr. Zhao has primarily worked on hydrodynamic simulations of flows in rivers, estuaries, and coastal oceans, and analyses of wastewater discharge from diffusers. He has experience in every step of the modeling process, including field data analysis, development and implementation of the computational model, and interpretation and presentation of simulation results.
Ben Martin, P.E. (VA)
Mr. Martin is currently a Principal Engineer at Flow Science and has been working with the company since 2005. He performs both CFD and hydraulic transient modeling. His CFD modeling includes water storage reservoirs and one-dimensional water quality modeling of lakes and reservoirs using DYRESM. Mr. Martin also has experience using U.S. EPA PLUMES and the three-dimensional ELCOM/CAEDYM models to evaluate mixing and dilution. His hydraulic modeling includes analysis of gravity flow and pressurized pipeline systems subject to pressure surges and waterhammer caused by pump power failure, pump startup/shutdown, control valve operation, and pipeline ruptures, plus sizing of appropriate surge control appurtenances.
