Hydrophobic/icephobic coatings based on thermal sprayed metallic layers with subsequent surface functionalization (2018)
Journal Article
Liu, J., Wang, J., Memon, H., Fu, Y., Barman, T., Choi, K., & Hou, X. (2019). Hydrophobic/icephobic coatings based on thermal sprayed metallic layers with subsequent surface functionalization. Surface and Coatings Technology, 357, 267-272. https://doi.org/10.1016/j.surfcoat.2018.10.002

Hydrophobic/icephobic coatings have been fabricated using a combination of thermal sprayed metallic MCrAlY (M = Ni, Co) coatings with a subsequent deposition process using 1H,1H,2H,2H-perfluorooctyltriethoxysilane (POTS). The MCrAlY coatings provide... Read More about Hydrophobic/icephobic coatings based on thermal sprayed metallic layers with subsequent surface functionalization.

Plasma virtual-roughness elements for cross-flow instability control (2018)
Journal Article
Choi, K., & Kim, J. (2018). Plasma virtual-roughness elements for cross-flow instability control. Experiments in Fluids, 59, Article 159. https://doi.org/10.1007/s00348-018-2609-x

Recent experiments and numerical simulations demonstrated that discrete roughness elements can be used to control cross-flow instability over a swept wing. Here, the application of this passive technique requires a row of thin cylindrical elements of... Read More about Plasma virtual-roughness elements for cross-flow instability control.

Development and evaluation of poly(dimethylsiloxane) based composite coatings for icephobic applications (2018)
Journal Article
Liu, J., Wang, J., Mazzola, L., Memon, H., Barman, T., Turnbull, B., …Hou, X. (2018). Development and evaluation of poly(dimethylsiloxane) based composite coatings for icephobic applications. Surface and Coatings Technology, 349, https://doi.org/10.1016/j.surfcoat.2018.06.066

Formation and accretion of ice on the leading edge surface of aircrafts wings may lead to disasters. The current de-icing system for aircraft will build up weight, increase energy consumption and add complexity to the aircraft systems. Development of...

Output feedback control of flow separation over an aerofoil using plasma actuators (2018)
Journal Article
Broglia, R., Choi, K., Houston, P., Pasquale, L., & Zanchetta, P. (2018). Output feedback control of flow separation over an aerofoil using plasma actuators. International Journal of Numerical Analysis and Modeling, 15(6),

We address the problem of controlling the unsteady flow separation over an aerofoil, using plasma actuators. Despite the complexity of the dynamics of interest, we show how the problem of controlling flow separation can be formulated as a simple set...

Mixed ice accretion on aircraft wings (2018)
Journal Article
Janjua, Z. A., Turnbull, B., Hibberd, S., & Choi, K. (in press). Mixed ice accretion on aircraft wings. Physics of Fluids, 30(2), https://doi.org/10.1063/1.5007301

Ice accretion is a problematic natural phenomenon that an effects a wide range of engineering applications including power cables, radio masts and wind turbines. Accretion on aircraft wings occurs when supercooled water droplets freeze instantaneousl... Read More about Mixed ice accretion on aircraft wings.
