At the ASME Fluids Engineering Division Summer Meeting (FEDSM 2025) in Philadelphia (July 27–30, 2025), our group presented seven papers spanning shock–droplet interactions, plasma-based icing control, freezing dynamics, and vortex-induced vibrations.
Highlights from Our Presentations:
- Development of a Simultaneous Gas/Droplet Imaging System for Characterizing Shock–Droplet Interactions Approaching a Solid Surface
T. J. Misztal, J. Ahumada Lazo, S. Kumar, and Y. Liu
Introduces a new imaging platform that captures both gas-phase and droplet dynamics during shock–droplet interactions, opening pathways to better understand high-speed multiphase flows relevant to propulsion and impact physics. - Dynamics of Supercooled Water Droplet Upon Impacting on Surface Dielectric Barrier Discharge Plasma
MD S. B. Sarwar, J. Ahumada Lazo, and Y. Liu
Explores how supercooled droplets interact with plasma-treated surfaces—an important step toward developing plasma-based anti-icing technologies for aerospace systems. - Development of a Novel Freezing-Levitation System for Producing Supercooled Droplet With Precise Control of Supercooling Degrees
MD S. B. Sarwar, H. Zhang, and Y. Liu
Presents a unique freezing-levitation platform that allows precise control of droplet supercooling, enabling systematic investigations of droplet freezing and icing processes. - Scaling Law–Based Analysis of Coalescence Dynamics of Colloidal Droplets on Substrates During the Freezing Process
H. Zhang, S. Kumar, and Y. Liu
Provides scaling-based insights into how colloidal droplets merge and freeze on surfaces, advancing understanding of freezing-based inkjet 3D printing and material solidification phenomena. - Dynamics of a Supercooled Water Droplet During In-Flight Interactions With a Dielectric Barrier Discharge Plasma
J. Ahumada Lazo, P. Lelikov, MD S. B. Sarwar, S. Kumar, and Y. Liu
Examines the real-time deformation, heating, and breakup of droplets exposed to plasma while airborne, with direct implications for active flow and icing control. - Thermal Effects and Dynamic Response of Droplet Impact on a Sliding Dielectric Barrier Discharge Plasma Actuator
J. Ahumada Lazo, P. Lelikov, MD S. B. Sarwar, S. Kumar, and Y. Liu
Investigates how plasma actuators alter the thermal and dynamic behavior of impacting droplets, supporting innovations in surface control and de-icing. - Dynamic Response and Force Analysis of a Vortex-Induced Cylinder Vibration: Insights Into Boundary Layer Pressure Distribution, Flow Structures, and Phase Dynamics
A. Fershalov, N. Elvin, I. Avros, P. Orlandini, and Y. Liu
Delivers new measurements of fluid–structure interactions in vortex-induced vibrations, shedding light on pressure distribution and vortex dynamics critical for offshore structures and energy devices.
We are proud of our team for advancing multiphase flow, plasma–droplet interaction, icing physics, and flow-induced vibration research, and for sharing these findings with the broader fluids engineering community at one of the premier conferences of the year.
