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.
