Jens H. M. Fransson

Jens H. M. Fransson is a Professor of Experimental Fluid Mechanics at KTH Royal Institute of Technology, Sweden, and holds a part-time professorship in Indoor Environment at the University of Gävle. He earned his master's degree in Engineering Physics (1999) and PhD in Fluid Mechanics (2004) from KTH, followed by promotion to Associate Professor (2007) and Full Professor (2013). His research focuses on experimental flow control, boundary layer transition, and turbulence, with applications in automotive and wind energy aerodynamics.

Fransson's work emphasizes delaying turbulence in boundary layers using innovative methods such as miniature vortex generators and spanwise velocity modulations. His ERC-funded AFRODITE project advanced passive flow control strategies. He has been awarded the Göran Gustafsson Prize twice (2005, 2008) and holds an ERC Starting Grant for AFRODITE.

His research has revealed that strategically placed surface features can suppress turbulence, reducing drag and emissions. Key areas include wind turbine wakes, bluff body flows, and canopy flows. Fransson teaches courses in fluid mechanics, aerodynamics, and vehicle design at KTH.
