Mechanisms of airfoil noise near stall conditions (2019)
Journal Article
Lacagnina, G., Chaitanya, P., Berk, T., Kim, J., Joseph, P., Ganapathisubramani, B., …Pinelli, A. (2019). Mechanisms of airfoil noise near stall conditions. Physical Review Fluids, 4(12), Article 123902. https://doi.org/10.1103/physrevfluids.4.123902

The focus of this paper is on investigating the noise produced by an airfoil at high angles of attack over a range of Reynolds number Re≈2×105–4×105. The objective is not modeling this source of noise but rather understanding the mechanisms of genera... Read More about Mechanisms of airfoil noise near stall conditions.

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.

Active fillers’ effect on in situ performances of foam bitumen recycled mixtures (2016)
Journal Article
Betti, G., Airey, G., Jenkins, K., Marradi, A., & Tebaldi, G. (in press). Active fillers’ effect on in situ performances of foam bitumen recycled mixtures. Road Materials and Pavement Design, 18(2), https://doi.org/10.1080/14680629.2016.1213486

Cold recycling is one of the most employed rehabilitation techniques for asphalt pavements and it is becoming more and more important as reducing emissions becomes a priority in the reduction of the greenhouse effect. The main advantages of asphalt c... Read More about Active fillers’ effect on in situ performances of foam bitumen recycled mixtures.
