Simo A. Mäkiharju is an Assistant Professor at UC Berkeley.  Prof. Mäkiharju’s undergraduate studies were in Energy Technology at the Lappeenranta University of Technology, Finland. In 2005 he received his Mechanical Engineering M.Sc. from the Ohio State University and his Ph.D. in 2012 from the University of Michigan. His graduate research focused on the reduction of hydrodynamic drag by gas injection and the development of a time-resolved x-ray densitometry imaging system for the study of multiphase flows. He continued at the University of Michigan as a Post-Doctoral Research Fellow (2012-2014) and as an Assistant Research Scientist (2014-2015) investigating single- and multiphase flow mixing in channel flows while continuing the development of x-ray based 2D and 3D flow measurement techniques. Starting as an Assistant Professor at UC Berkeley in January of 2016, he is continuing to pursue his research interest in advancing the physical understanding of high-Reynolds number single- and multiphase flows through experimental research, primarily through the development and use of advanced experimental techniques.


Research Description:

One of the central objectives of Professor Mäkiharju’s research is to advance the physical understanding of high Reynolds number single- and multiphase flows primarily through experimental research, and through the development and use of advanced experimental techniques. Multiphase flows are encountered in almost every aspect of modern life, including offshore applications, biological flows, energy production, chemical processing, and naval hydrodynamics. Specific topics Professor Mäkiharju has worked on include the reduction drag on marine vehicles, mitigation of damage and noise caused by cavitation in naval and industrial applications, and efficient handling of single- and multiphase flows in energy production applications.
