Credentials

Ph.D. – Mechanical Engineering, University at Buffalo, The State University of New York, 2000
M.S. – Aerospace Engineering, University at Buffalo, The State University of New York, 1994
B.S. equivalent – Mechanical Engineering, Technical University of Darmstadt, Germany, 1992

Prof. Martin Wosnik joined the Mechanical Engineering faculty in the spring of 2008. Prior to the appointment at UNH, he was Senior Flow Engineer at Alden Research Laboratory in Massachusetts, a national flow engineering firm conducting a wide variety of hydraulic studies for electric power utilities, architect-engineering firms, equipment manufacturers, and governmental agencies. Before that, he worked as Research Associate at St. Anthony Falls Laboratory at the University of Minnesota, and as Assistant Research Professor in the Thermo and Fluid Dynamics Section at Chalmers University of Technology in Gothenburg, Sweden.

Prof. Wosnik's research interests are in the area of fluid and thermal science and engineering, and include experiment and theory of wall-bounded turbulent flows, cavitation and bubbly flows, high-speed hydrodynamics, flow measurement, hydraulic modeling and alternative energy applications.

Prof. Wosnik is teaching fluid mechanics and heat transfer courses, including ME 906 Convection Heat Transfer and ME 705 Thermal System Design
