Non-stationary regimes of surface gravity wave turbulence (2013)
Journal Article
Bedard, R., Nazarenko, S., & Lukaschuk, S. (2013). Non-stationary regimes of surface gravity wave turbulence. JETP Letters, 97(8), (459-465). doi:10.1134/S0021364013080055. ISSN 0021-3640

We present experimental results about rising and decaying gravity wave turbulence in a large laboratory flume. We consider the time evolution of the wave energy spectral components in ω- and k-domains and demonstrate that emerging wave turbulen... Read More

Statistics of surface gravity wave turbulence in the space and time domains (2009)
Journal Article

We present experimental results on simultaneous spacetime measurements for the gravity wave turbulence in a large laboratory flume. We compare these results with predictions of the weak turbulence theory (WTT) based on random waves, as well as with p... Read More

Gravity wave turbulence in wave tanks: Space and time statistics (2009)
Journal Article
Lukaschuk, S., Nazarenko, S., McLelland, S., & Denissenko, P. (2009). Gravity wave turbulence in wave tanks: Space and time statistics. Physical review letters, 103(4), doi:10.1103/PhysRevLett.103.044501

We present the first simultaneous space-time measurements for gravity wave turbulence in a large laboratory flume. We found that the slopes of k and ω wave spectra depend on wave intensity. This cannot be explained by any existing theory considering... Read More

Laboratory studies of near-grazing impulsive sound propagating over rough water (2008)
Journal Article
Qin, Q., Lukaschuk, S., & Attenborough, K. (2008). Laboratory studies of near-grazing impulsive sound propagating over rough water. The Journal of the Acoustical Society of America, 124(2), (EL40-EL44). doi:10.1121/1.2947627. ISSN 0001-4966

Acoustic impulses due to an electrical spark source (main acoustic energy near 15 kHz) have been measured after propagating near to the water surface in a shallow container resting on a vibrating platform. Control of the platform vibration enabled co... Read More

Surface tension: Floater clustering in a standing wave (2005)
Journal Article
Weinberg, A., Falkovich, G., Denissenko, P., & Lukaschuk, S. (2005). Surface tension: Floater clustering in a standing wave. Nature, 435(7045), 1045-1046. doi:10.1038/4351045a

How do waves affect the distribution of small particles that float on water? Here we show that drifting small particles concentrate in either the nodes or antinodes of a standing wave, depending on whether they are hydrophilic or hydrophobic, as a re... Read More
