Research Interests

Experimental fluid mechanics and heat transfer
* Microfluids * Plasma deposition * Turbulent flows

Professor Wroblewski’s research program is focused on experiments and modeling of fluid-thermal transport phenomenon, with two areas of active interest.  The first involves a multi-disciplinary effort, encompassing fundamental issues in thermal-fluids, controls and materials to formulate the knowledge base necessary for implementing advanced feedback control for plasma spray for thermal barrier coatings.

His work has included modeling and simulation of rapid solidification, experimental characterization of thermal-fluid interactions in plasma spray field, and development of new sensor concepts for spray pattern diagnosis.  The second area involves collaboration with the Air Force Research Laboratory, NOAA, and Airborne Research of Australia to study turbulence in the upper troposphere and lower stratosphere and its effect on Aerospace systems.   He has participated in several field measurement campaigns that employ aircraft instrumented with fast-response, high resolution turbulence probe, to characterize both large-scale two-dimensional coherent structures and small scale three-dimensional turbulence in and around the sub-tropical jet stream.
