Thermal Footprints of Rough Walls
Experimental investigation of turbulent heat transfer over roughness transitions using IR thermography and cold-wire anemometry.
Designed and built a modular heated-wall boundary layer test section with IR-transparent window, 12+ embedded thermocouples, integrated cold-wire probe, and high-temperature roughness elements fabricated via metal 3D printing (selective laser sintering).
Developed calibration protocols for cold-wire anemometry achieving 0.05 °C uncertainty; built Python pipelines to synchronize thermal, pressure, and flow sensors at 10 kHz for time-resolved thermal measurements.
Characterizing the effect of outer-layer turbulence on internal scalar boundary layer development and the thermal footprint at the wall over roughness transitions.
